Overview ¶

Package anchor computes the 8-byte discriminators the Anchor framework writes at the start of instruction data and program account data. It is pure logic over crypto/sha256 with no dependency on the rest of the SDK.

Functions ¶

func AccountDisc ¶

func AccountDisc(name string) [8]byte

AccountDisc returns the 8-byte tag Anchor writes at the start of a program account's data: sha256("account:" + name)[:8]. name is the PascalCase Rust struct (e.g. "Pool", "UserPosition").

func MethodDisc ¶

func MethodDisc(name string) [8]byte

MethodDisc returns the 8-byte discriminator Anchor emits at the start of an instruction's data: sha256("global:" + name)[:8]. name is the snake_case Rust method on the program (e.g. "initialize", "swap").

func Sighash ¶

func Sighash(namespace, name string) [8]byte

Sighash returns the first 8 bytes of sha256(namespace + ":" + name). Anchor uses this scheme for several discriminators; MethodDisc and AccountDisc wrap it with the common namespaces. Exposed for non-standard namespaces (e.g. "state:" on legacy state methods).
