Trait sugar_cli::common::Signer

pub trait Signer {
    // Required methods
    fn try_pubkey(&self) -> Result<Pubkey, SignerError>;
    fn try_sign_message(&self, message: &[u8]) -> Result<Signature, SignerError>;
    fn is_interactive(&self) -> bool;

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

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>

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

Provided Methods

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.

Trait Implementations

impl Debug for dyn Signer + 'static

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

Formats the value using the given formatter.

impl PartialEq<dyn Signer + 'static> for dyn Signer + 'static

fn eq(&self, other: &dyn Signer) -> 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 !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
