Functions

func IsPushOnly

func IsPushOnly(pops []ParsedOpcode) bool

IsPushOnly returns true if the script only pushes data, false otherwise.

Types

type ParsedOpcode

type ParsedOpcode struct {
	Opcode opcode.Opcode
	Data   []byte
}

ParsedOpcode represents an opcode that has been parsed and includes any potential data associated with it.

func ParseScript

func ParseScript(script []byte) ([]ParsedOpcode, er.R)

parseScript preparses the script in bytes into a list of parsedOpcodes while applying a number of sanity checks.

func ParseScriptTemplate

func ParseScriptTemplate(script []byte, opcodes map[byte]opcode.Opcode) ([]ParsedOpcode, er.R)

ParseScriptTemplate is the same as ParseScript but allows the passing of the template list for testing purposes. When there are parse errors, it returns the list of parsed opcodes up to the point of failure along with the error.
