Struct NullSigner

pub struct NullSigner { /* private fields */ }

Available on crate feature full only.

NullSigner - A Signer implementation that always produces Signature::default(). Used as a placeholder for absentee signers whose ’Pubkey` is required to construct the transaction

Implementations

impl NullSigner

pub fn new(pubkey: &Address) -> NullSigner

Trait Implementations

impl Clone for NullSigner

fn clone(&self) -> NullSigner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullSigner

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

Formats the value using the given formatter.

impl Default for NullSigner

fn default() -> NullSigner

Returns the “default value” for a type.

impl<T> PartialEq<T> for NullSigner

where T: Signer,

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Signer for NullSigner

fn try_pubkey(&self) -> Result<Address, 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 implementation requires user interaction to sign

fn pubkey(&self) -> Address

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.
