Variables ¶
var ( // ErrMissingExportedParamName is returned when exported contract method has unnamed parameter. ErrMissingExportedParamName = errors.New("exported method is not allowed to have unnamed parameter") // ErrInvalidExportedRetCount is returned when exported contract method has invalid return values count. ErrInvalidExportedRetCount = errors.New("exported method is not allowed to have more than one return value") )
Various exported functions usage errors.
var ErrUnsupportedTypeAssertion = errors.New("type assertion with two return values is not supported")
ErrUnsupportedTypeAssertion is returned when type assertion statement is not supported by the compiler.
Functions ¶
func Compile ¶
Compile compiles a Go program into a bytecode that can run on the Neo virtual machine. If `r != nil`, `name` is interpreted as a filename, and `r` as file contents. Otherwise `name` is either a file name or a name of the directory containing source files.
func CompileAndSave ¶
CompileAndSave will compile and save the file to disk in the NEF format.
Types ¶
type DebugInfo ¶ added in v0.75.0
type DebugInfo struct {
MainPkg string `json:"-"`
Hash util.Uint160 `json:"hash"`
Documents []string `json:"documents"`
Methods []MethodDebugInfo `json:"methods"`
// NamedTypes are exported structured types that have some name (even
// if the original structure doesn't) and a number of internal fields.
NamedTypes map[string]binding.ExtendedType `json:"-"`
Events []EventDebugInfo `json:"events"`
// EmittedEvents contains events occurring in code.

type DebugSeqPoint struct {
// Opcode is an opcode's address.
Opcode int
// Document is an index of file where sequence point occurs.
Document int
// StartLine is the first line of the break-pointed statement.
StartLine int
// StartCol is the first column of the break-pointed statement.
StartCol int
// EndLine is the last line of the break-pointed statement.
EndLine int
// EndCol is the last column of the break-pointed statement.
EndCol int
}
DebugSeqPoint represents break-point for debugger.

}
EventDebugInfo represents smart-contract's event debug information.
type MethodDebugInfo ¶ added in v0.75.0
type MethodDebugInfo struct {
// ID is the actual name of the method.
ID string `json:"id"`
// Name is the name of the method with the first letter in a lowercase
// together with the namespace it belongs to. We need to keep the first letter
// lowercased to match manifest standards.
Name DebugMethodName `json:"name"`
