Types ¶

type ViewContext ¶ added in v0.3.0

type ViewContext struct {
	// contains filtered or unexported fields
}

ViewContext implements the needed infrastructure to run external view calls, its more lightweight than vmcontext

func New ¶

func New(ch chain.ChainCore, stateReader state.State) (*ViewContext, error)

func (*ViewContext) AccountID ¶ added in v0.3.0

func (ctx *ViewContext) AccountID() isc.AgentID

func (*ViewContext) Call ¶ added in v0.3.0

func (ctx *ViewContext) Call(targetContract, epCode isc.Hname, params dict.Dict, _ *isc.Assets) dict.Dict

func (*ViewContext) CallViewExternal ¶ added in v0.3.0

func (ctx *ViewContext) CallViewExternal(targetContract, epCode isc.Hname, params dict.Dict) (ret dict.Dict, err error)

CallViewExternal calls a view from outside the VM, for example API call

func (*ViewContext) Caller ¶ added in v1.0.3

func (ctx *ViewContext) Caller() isc.AgentID

func (*ViewContext) ChainID ¶ added in v0.3.0

func (ctx *ViewContext) ChainID() isc.ChainID

func (*ViewContext) ChainInfo ¶ added in v1.0.3

func (ctx *ViewContext) ChainInfo() *isc.ChainInfo

func (*ViewContext) ChainOwnerID ¶ added in v0.3.0

func (ctx *ViewContext) ChainOwnerID() isc.AgentID

func (*ViewContext) CurrentContractHname ¶ added in v0.3.0

func (ctx *ViewContext) CurrentContractHname() isc.Hname

func (*ViewContext) Debugf ¶ added in v0.3.0

func (ctx *ViewContext) Debugf(format string, params ...interface{})

func (*ViewContext) GasBudgetLeft ¶ added in v0.3.0

func (ctx *ViewContext) GasBudgetLeft() uint64

func (*ViewContext) GasBurn ¶ added in v0.3.0

func (ctx *ViewContext) GasBurn(burnCode gas.BurnCode, par ...uint64)

func (*ViewContext) GasBurnEnable ¶ added in v0.3.0

func (ctx *ViewContext) GasBurnEnable(enable bool)

func (*ViewContext) GasBurnLog ¶ added in v0.3.0

func (ctx *ViewContext) GasBurnLog() *gas.BurnLog

only for debugging

func (*ViewContext) GasBurned ¶ added in v0.3.7

func (ctx *ViewContext) GasBurned() uint64

func (*ViewContext) GetAccountNFTs ¶ added in v0.3.0

func (ctx *ViewContext) GetAccountNFTs(agentID isc.AgentID) []iotago.NFTID

func (*ViewContext) GetBaseTokensBalance ¶ added in v0.3.0

func (ctx *ViewContext) GetBaseTokensBalance(agentID isc.AgentID) uint64

func (*ViewContext) GetBlockProof ¶ added in v0.3.0

func (ctx *ViewContext) GetBlockProof(blockIndex uint32) ([]byte, *trie.MerkleProof, error)

GetBlockProof returns: - blockInfo record in serialized form - proof that the blockInfo is stored under the respective key. Useful for proving commitment to the past state, because blockInfo contains commitment to that block

func (*ViewContext) GetContractRecord ¶ added in v0.3.0

func (ctx *ViewContext) GetContractRecord(contractHname isc.Hname) (ret *root.ContractRecord)

func (*ViewContext) GetContractStateCommitment ¶ added in v0.3.0

func (ctx *ViewContext) GetContractStateCommitment(hn isc.Hname) ([]byte, error)

GetContractStateCommitment returns commitment to the contract's state, if possible. To be able to retrieve state commitment for the contract's state, the state must contain values of contracts hname at its nil key. Otherwise, function returns error

func (*ViewContext) GetMerkleProof ¶ added in v0.3.0

func (ctx *ViewContext) GetMerkleProof(key []byte) (ret *trie.MerkleProof, err error)

GetMerkleProof returns proof for the key. It may also contain proof of absence of the key

func (*ViewContext) GetNFTData ¶ added in v0.3.0

func (ctx *ViewContext) GetNFTData(nftID iotago.NFTID) *isc.NFT

func (*ViewContext) GetNativeTokenBalance ¶ added in v0.3.0

func (ctx *ViewContext) GetNativeTokenBalance(agentID isc.AgentID, nativeTokenID iotago.NativeTokenID) *big.Int

func (*ViewContext) GetNativeTokens ¶ added in v1.0.3

func (ctx *ViewContext) GetNativeTokens(agentID isc.AgentID) iotago.NativeTokens

func (*ViewContext) GetRootCommitment ¶ added in v0.3.0

func (ctx *ViewContext) GetRootCommitment() trie.Hash

GetRootCommitment calculates root commitment from state. A valid state must return root commitment equal to the L1Commitment from the anchor

func (*ViewContext) Infof ¶ added in v0.3.0

func (ctx *ViewContext) Infof(format string, params ...interface{})

func (*ViewContext) LocateProgram ¶ added in v0.3.0

func (ctx *ViewContext) LocateProgram(programHash hashing.HashValue) (vmtype string, binary []byte, err error)

func (*ViewContext) Panicf ¶ added in v0.3.0

func (ctx *ViewContext) Panicf(format string, params ...interface{})

func (*ViewContext) Params ¶ added in v0.3.0

func (ctx *ViewContext) Params() *isc.Params

func (*ViewContext) Processors ¶ added in v0.3.0

func (ctx *ViewContext) Processors() *processors.Cache

func (*ViewContext) StateReader ¶ added in v0.3.0

func (ctx *ViewContext) StateReader() kv.KVStoreReader

func (*ViewContext) Timestamp ¶ added in v0.3.0

func (ctx *ViewContext) Timestamp() time.Time
