Struct MemorySigner 

pub struct MemorySigner { /* private fields */ }

A Solana-based signer that uses an in-memory keypair

Implementations

impl MemorySigner

pub fn new(keypair: Keypair) -> Self

Creates a new signer from a Solana keypair

pub fn from_bytes(private_key: &[u8]) -> Result<Self, SignerError>

Creates a new signer from a private key byte array

pub fn from_private_key_string(private_key: &str) -> Result<Self, SignerError>

Creates a new signer from a private key string that can be in multiple formats:

• Base58 encoded string
• U8Array format: “[0, 1, 2, …]”
• File path to a JSON keypair file

Trait Implementations

impl Debug for MemorySigner

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

Formats the value using the given formatter.

impl SolanaSigner for MemorySigner

fn pubkey(&self) -> Pubkey

Get the public key of this signer

fn sign_transaction<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 mut Transaction, ) -> Pin<Box<dyn Future<Output = Result<SignedTransaction, SignerError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Sign a Solana transaction

fn sign_message<'life0, 'life1, 'async_trait>( &'life0 self, message: &'life1 [u8], ) -> Pin<Box<dyn Future<Output = Result<Signature, SignerError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Sign an arbitrary message

fn sign_partial_transaction<'life0, 'life1, 'async_trait>( &'life0 self, tx: &'life1 mut Transaction, ) -> Pin<Box<dyn Future<Output = Result<SignedTransaction, SignerError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Partially sign a transaction and return it as a base64-encoded string

fn is_available<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check if the signer is available and healthy
