Struct solana_sdk::signer::presigner::Presigner

pub struct Presigner { /* fields omitted */ }

A Signer implementation that represents a Signature that has been constructed externally. Performs a signature verification against the expected message upon sign() requests to affirm its relationship to the message bytes

Implementations

impl Presigner

pub fn new(pubkey: &Pubkey, signature: &Signature) -> Self

Trait Implementations

impl Clone for Presigner

fn clone(&self) -> Presigner

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Presigner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Presigner

fn default() -> Presigner

Returns the “default value” for a type.

impl<T> PartialEq<T> for Presigner where
    T: Signer, 

fn eq(&self, other: &T) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl Signer for Presigner

fn try_pubkey(&self) -> Result<Pubkey, SignerError>

Fallibly gets the implementor’s public key

fn try_sign_message(&self, message: &[u8]) -> Result<Signature, SignerError>

Fallibly produces an Ed25519 signature over the provided message bytes.

fn is_interactive(&self) -> bool

Whether the impelmentation requires user interaction to sign

fn pubkey(&self) -> Pubkey

Infallibly gets the implementor’s public key. Returns the all-zeros Pubkey if the implementor has none.

fn sign_message(&self, message: &[u8]) -> Signature

Infallibly produces an Ed25519 signature over the provided message bytes. Returns the all-zeros Signature if signing is not possible.
