Trait solana_sdk::signer::Signer[−][src]

pub trait Signer {
    fn try_pubkey(&self) -> Result<Pubkey, SignerError>;

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

Expand description

The Signer trait declares operations that all digital signature providers must support. It is the primary interface by which signers are specified in Transaction signing interfaces

Required methods

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

Fallibly gets the implementor’s public key

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

Fallibly produces an Ed25519 signature over the provided message bytes.

Provided methods

fn pubkey(&self) -> Pubkey[src]

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

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

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