Functions

func DetectBigmapTypes 

func DetectBigmapTypes(typ Prim) map[string]Type

Returns a map of all known bigmap type definitions inside a given prim. Keys are derived from type annotations. Unlabeled bigmaps are prefixed `bigmap_` followed by a unique sequence number. Duplicate names are prevented by adding by a unique sequence number as well.

func DetectBigmaps 

func DetectBigmaps(typ Prim, storage Prim) map[string]int64

Returns a map of named bigmap ids obtained from a storage type and a storage value. In the edge case where a T_OR branch hides an exsting bigmap behind a None value, the hidden bigmap is not detected.

func DisableLog 

func DisableLog()

DisableLog disables all library log output. Logging output is disabled by default until either UseLogger or SetLogWriter are called.

func IsEqualPrim 

func IsEqualPrim(p1, p2 Prim, withAnno bool) bool

func IsManagerTz 

func IsManagerTz(buf []byte) bool

func KeyHash 

func KeyHash(buf []byte) tezos.ExprHash

func Trace 

func Trace(fn func(log LogFn))

Trace is a function closure wrapper that forwards trace calls to an output function if set. Call UseTrace() to set a function of type LogFn

func UnmarshalScriptType 

func UnmarshalScriptType(data []byte) (param Type, storage Type, err error)

UnmarshalScriptType is an optimized binary unmarshaller which decodes type trees only. Use this to access smart contract types when script and storage are not required.

func UseLogger 

func UseLogger(logger logpkg.Logger)

UseLogger uses a specified Logger to output package logging info. This should be used in preference to SetLogWriter if the caller is also using logpkg.

func (m Interface) Matches(e Entrypoints) bool

Checks if a contract implements all entrypoints required by a standard interface without requiring argument labels to match. This is a looser definition of interface compliance, but in line with the Michelson type system which ignores annotation labels for type equality.

This check uses extracted Typedefs to avoid issues when the Micheline primitive structure diverges from the defined interface (e.g. due to comb type unfolding).

func (Interface) MatchesStrict 

func (m Interface) MatchesStrict(e Entrypoints) bool

Checks if a contract strictly implements all standard interface entrypoints including argument types and argument names (annotations).

This check uses extracted Typedefs to avoid issues when the Micheline primitive structure diverges from the defined interface (e.g. due to comb type unfolding).

func (Typedef) Marshal 

func (t Typedef) Marshal(v any, optimized bool) (Prim, error)

Marshal takes a scalar or nested Go type and populates a Micheline primitive tree compatible with type t. This method is compatible with most contract entrypoints, contract storage, bigmap values, etc. Use optimized to control whether the target prims contain values in optimized form (binary addresses, numeric timestamps) or string form.

Note: This is work in progress. Several data types are still unsupported and entrypoint mapping requires some extra boilerplate: 

// Entrypoint example (without error handling for brevity)
eps, _ := script.Entrypoints(true)
ep, _ := eps["name"]

// marshal to prim tree
// Note: be mindful of the way entrypoint typedefs are structured:
// - 1 arg: use scalar value in ep.Typedef[0]
// - >1 arg: use entire list in ep.Typedef but wrap into struct
typ := ep.Typedef[0]
if len(ep.Typedef) > 1 {
    typ = micheline.Typedef{
        Name: micheline.CONST_ENTRYPOINT,
        Type: micheline.TypeStruct,
        Args: ep.Typedef,
    }
}

// then use the type to marshal into primitives
prim, err := typ.Marshal(args, true)
