Convenience trait for working with mixed collections of Signers

Required Methods

fn pubkeys(&self) -> Vec<Pubkey>

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

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

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

fn is_interactive(&self) -> bool

Implementors

impl<T: ?Sized, S: Signer + ?Sized> Signers for T

where for<'a> &'a T: IntoIterator<Item = &'a S>,

Any T where T impls IntoIterator yielding Signers implements Signers.

This includes [&dyn Signer], [Box<dyn Signer>], [&dyn Signer; N], Vec<dyn Signer>, Vec<Keypair>, etc.

When used as a generic function param, &T should be used instead of T where T: Signers, due to the ?Sized bounds on T. E.g. Signer implements Signers, but &[Signer] does not
