Struct SigningMessage 

pub struct SigningMessage { /* private fields */ }

An opaque, frozen transaction signing message: the exact bytes M an external signer signs (48 bytes), the fee-payer key the signature must verify under (derived from the body, never independent caller input), and an immutable snapshot of the body so attach_signature can emit a self-consistent signed wire even if the caller later mutates its original buffer.

Implementations

impl SigningMessage

pub fn as_bytes(&self) -> &[u8]

The exact bytes to sign — hand these to the HSM/MPC backend.

pub fn expected_pubkey(&self) -> &[u8; 32]

The public key the signature must verify under: the fee-payer taken from the transaction body, so it cannot disagree with what the chain checks.

pub fn body(&self) -> &[u8]

The transaction body snapshot these bytes were built from.

Trait Implementations

impl Clone for SigningMessage

fn clone(&self) -> SigningMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
