func NewAccountPublicKey(publicKey *runtime.PublicKey,
	hashAlgo sema.HashAlgorithm,
	keyIndex int,
	weight int,
) (*flow.AccountPublicKey, error)

NewAccountPublicKey construct an account public key given a runtime public key.

Types

type AccountKeyHandler added in v0.17.6 

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

AccountKeyHandler handles all interaction with account keys such as get/set/revoke

func NewAccountKeyHandler added in v0.17.6 

func NewAccountKeyHandler(accounts state.Accounts) *AccountKeyHandler

func (*AccountKeyHandler) AddAccountKey added in v0.17.6 

func (h *AccountKeyHandler) AddAccountKey(address runtime.Address,
	publicKey *runtime.PublicKey,
	hashAlgo runtime.HashAlgorithm,
	weight int,

	*runtime.AccountKey,
	error,
)

AddAccountKey adds a public key to an existing account.

This function returns an error if the specified account does not exist or if the key insertion fails.

func (*AccountKeyHandler) AddEncodedAccountKey added in v0.17.6 

func (e *AccountKeyHandler) AddEncodedAccountKey(address runtime.Address, encodedPublicKey []byte) (err error)

AddEncodedAccountKey adds an encoded public key to an existing account.

This function returns following error * NewAccountNotFoundError - if the specified account does not exist * ValueError - if the provided encodedPublicKey is not valid public key

func (*AccountKeyHandler) GetAccountKey added in v0.17.6 

func (h *AccountKeyHandler) GetAccountKey(address runtime.Address, keyIndex int) (*runtime.AccountKey, error)

GetAccountKey retrieves a public key by index from an existing account.

This function returns a nil key with no errors, if a key doesn't exist at the given index. An error is returned if the specified account does not exist, the provided index is not valid, or if the key retrieval fails.

func (*AccountKeyHandler) RemoveAccountKey added in v0.17.6 

func (e *AccountKeyHandler) RemoveAccountKey(address runtime.Address, keyIndex int) (encodedPublicKey []byte, err error)

RemoveAccountKey revokes a public key by index from an existing account.

This function returns an error if the specified account does not exist, the provided key is invalid, or if key revoking fails.

func (*AccountKeyHandler) RevokeAccountKey added in v0.17.6 

func (h *AccountKeyHandler) RevokeAccountKey(address runtime.Address, keyIndex int) (*runtime.AccountKey, error)

This function returns a nil key with no errors, if a key doesn't exist at the given index. An error is returned if the specified account does not exist, the provided index is not valid, or if the key revoking fails. TODO (ramtin) do we have to return runtime.AccountKey for this method or can be separated into another method

type ProgramsHandler added in v0.15.0 

type ProgramsHandler struct {
	Programs *programs.Programs
	// contains filtered or unexported fields
}

ProgramsHandler manages operations using Programs storage. It's separation of concern for hostEnv Cadence contract guarantees that Get/Set methods will be called in a LIFO manner, so we use stack based approach here. During successful execution stack should be cleared naturally, making cleanup method essentially no-op. But if something goes wrong, all nested views must be merged in order to make sure they are recorded
