Types

type Deal 

type Deal struct {
	// this is the cid of the deal where ID is set to empty string
	ID            string        `json:"id"`
	Members       DealMembers   `json:"members"`
	Pricing       DealPricing   `json:"pricing"`
	Timeouts      DealTimeouts  `json:"timeouts"`
	JobOffer      JobOffer      `json:"job_offer"`
	ResourceOffer ResourceOffer `json:"resource_offer"`
}

this is the struct that will have it's ID taken and used as the reference for what both parties agreed to the solver will publish this deal to the directory

func GetDeal 

func GetDeal(
	jobOffer JobOffer,
	resourceOffer ResourceOffer,
) (Deal, error)

type DealContainer 

type DealContainer struct {

type DealTimeouts struct {
	Agree          DealTimeout `json:"agree"`
	SubmitResults  DealTimeout `json:"submit_results"`
	JudgeResults   DealTimeout `json:"judge_results"`
	MediateResults DealTimeout `json:"mediate_results"`
}

	TimeoutAgree         string `json:"timeout_agree"`
	TimeoutSubmitResult  string `json:"timeout_submit_result"`
	TimeoutMediateResult string `json:"timeout_mediate_result"`
}

we keep track of tx ids on behalf of resource providers and job creators - we use these to "marK" a deal as having had a transaction submitted but that tx has not yet been included in a block - therefore, we let the job creator & resource provider update these at will

type DealTransactionsMediator 

type DealTransactionsMediator struct {
	MediationAcceptResult string `json:"mediation_accept_result"`
	MediationRejectResult string `json:"mediation_reject_result"`
}

	TimeoutAgree         string `json:"timeout_agree"`
	TimeoutJudgeResult   string `json:"timeout_judge_result"`
	TimeoutMediateResult string `json:"timeout_mediate_result"`
}

type JobOffer 

type JobOffer struct {
	// this is the cid of the job offer where ID is set to empty string
	ID string `json:"id"`
	// this is basically a nonce so we don't have one ID pointing at multiple offers
	CreatedAt int `json:"created_at"`
	// the address of the job creator
	JobCreator string `json:"job_creator"`
	// the actual module that is being offered
	// this must hash to the ModuleID above
	Module ModuleConfig `json:"module"`
	// the spec required by the module
	// this will have been hoisted from the module itself
	Spec MachineSpec `json:"spec"`
	// the user inputs to the module
	// these values will power the go template
	Inputs map[string]string `json:"inputs"`
	// tells the solver how to match these prices
	// for JC this will normally be MarketPrice
	Mode PricingMode `json:"mode"`
	// the offered price and timeouts
	Pricing  DealPricing  `json:"pricing"`
	Timeouts DealTimeouts `json:"timeouts"`

	// which parties are trusted by the job creator
	Services ServiceConfig `json:"trusted_parties"`
}

posted to the solver by a job creator

type JobOfferContainer 

type JobOfferContainer struct {
	ID         string   `json:"id"`
	DealID     string   `json:"deal_id"`
	JobCreator string   `json:"job_creator"`
	State      uint8    `json:"state"`
	JobOffer   JobOffer `json:"job_offer"`
}

this is what the solver keeps track of so we can know what the current state of the deal is

func GetJobOfferContainer 

func GetJobOfferContainer(
	jobOffer JobOffer,
) JobOfferContainer

type MachineSpec 

type MachineSpec struct {
	// Milli-GPU
	// Whilst it's unlikely that partial GPU's make sense
	// let's not use a float and fix the precision to 1/1000
	GPU int `json:"gpu"`

	// Milli-CPU
	CPU int `json:"cpu"`

	// Megabytes
	RAM int `json:"ram"`
}

used by resource providers to describe their resources use by job offers to describe their requirements when used by resource providers - these are absolute values when used by job offers - these are minimum requirements

type MatchDecision 

type MatchDecision struct {
	JobOffer      string `json:"job_offer"`
	ResourceOffer string `json:"resource_offer"`
	Deal          string `json:"deal"`
	Result        bool   `json:"result"`
}

represents a solver decision the solver keeps track of "no" decisions to avoid trying to repeatedly match things it's already decided it can't match

type Module 

type Module struct {
	// the min spec that this module requires
	// e.g. does this module need a GPU?
	// the module file itself will contain this spec
	// and so the module will need to be downloaded
	// and executed for this spec to be known
	Machine MachineSpec `json:"machine"`

	// the bacalhau job spec
	Job bacalhau.Job `json:"job"`
}

this is what is loaded from the template file in the git repo

type ModuleConfig 

type ModuleConfig struct {

	// used for the shortcuts
	// this is in the modules package
	// where we keep a map of named modules
	// and their versions onto the
	// repo, hash and path below
	Name string `json:"name"`

	// needs to be a http url for a git repo
	// we must be able to clone it without credentials
	Repo string `json:"repo"`
	// the git hash to pin the module
	// we will 'git checkout' this hash
	Hash string `json:"hash"`
	// once the checkout has been done
	// this is the path to the module template
	// within the repo
	Path string `json:"path"`
}

describes a workload to be run this pins a go-template.yaml file that is a bacalhau job spec

type PricingMode 

type PricingMode string

MarketPrice means - get me the best deal job creators will do this by default i.e. "just buy me the cheapest" FixedPrice means - take it or leave it resource creators will do this by default i.e. "this is my price" 

const (
	MarketPrice PricingMode = "MarketPrice"
	FixedPrice  PricingMode = "FixedPrice"
)

type ResourceOffer 

type ResourceOffer struct {
	// this is the cid of the resource offer where ID is set to empty string
	ID string `json:"id"`
	// this is basically a nonce so we don't have one ID pointing at multiple offers
	CreatedAt int `json:"created_at"`
	// the address of the job creator
	ResourceProvider string `json:"resource_provider"`
	// allows a resource provider to manage multiple offers
	// that are essentially the same
	Index int `json:"index"`
	// the spec being offered
	Spec MachineSpec `json:"spec"`
	// the module ID's that this resource provider can run
	// an empty list means ALL modules
	Modules []string `json:"modules"`
	// tells the solver how to match these prices
	// for RP this will normally be FixedPrice
	// we expect the default pricing to be filled in
	Mode PricingMode `json:"mode"`
	// the default pricing for this resource offer
	// i.e. this is for any module
	DefaultPricing  DealPricing  `json:"default_pricing"`
	DefaultTimeouts DealTimeouts `json:"default_timeouts"`
	// the pricing for each module
	// this allows a resource provider to charge more
	// for certain modules
	ModulePricing  map[string]DealPricing  `json:"module_pricing"`
	ModuleTimeouts map[string]DealTimeouts `json:"module_timeouts"`

	// which parties are trusted by the resource provider
	Services ServiceConfig `json:"trusted_parties"`
}

posted to the solver by a resource provider

type ResourceOfferContainer 

type ResourceOfferContainer struct {
	ID               string        `json:"id"`
	DealID           string        `json:"deal_id"`
	ResourceProvider string        `json:"resource_provider"`
	State            uint8         `json:"state"`
	ResourceOffer    ResourceOffer `json:"job_offer"`
}

this is what the solver keeps track of so we can know what the current state of the deal is

func GetResourceOfferContainer 

func GetResourceOfferContainer(
	resourceOffer ResourceOffer,
) ResourceOfferContainer

type Result 

type Result struct {
	// this is the cid of the result where ID is set to empty string
	ID     string `json:"id"`
	DealID string `json:"deal_id"`
	// the CID of the actual results
	DataID           string `json:"results_id"`
	Error            string `json:"error"`
	InstructionCount uint64 `json:"instruction_count"`
}

type ServiceConfig 

type ServiceConfig struct {
	Solver   string   `json:"solver"`
	Mediator []string `json:"mediator"`
