Struct LocalSigner 

pub struct LocalSigner { /* private fields */ }

Signs with an in-memory keypair via arch_sdk::sign_message_bip322.

Implementations

impl LocalSigner

pub fn new(keypair: UntweakedKeypair) -> Self

Wraps an in-memory keypair, with the network defaulting to Bitcoin.

pub fn from_key_file(path: &str) -> Result<Self, SignError>

Loads a keypair from a file in arch_sdk::with_secret_key_file format: a hex-encoded secret key or a JSON byte array.

Never generates or writes a key.

Errors

SignError::Config when the file is unreadable or does not parse as a secret key.

pub fn with_network(self, network: Network) -> Self

Returns this signer with network used for BIP322 digests.

pub fn pubkey(&self) -> Pubkey

Returns the Arch account key derived from the wrapped keypair.

pub fn network(&self) -> Network

Returns the network used for BIP322 digests.

Trait Implementations

impl ArchSignerT for LocalSigner

fn pubkey(&self) -> Pubkey

Returns the Arch account key this signer signs for.

fn sign_message<'life0, 'life1, 'async_trait>( &'life0 self, message: &'life1 ArchMessage, ) -> Pin<Box<dyn Future<Output = Result<SignResponse, SignError>> + Send + 'async_trait>>

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

Signs the message’s BIP322 digest.

fn sign_messages<'life0, 'life1, 'async_trait>( &'life0 self, messages: &'life1 [ArchMessage], ) -> Pin<Box<dyn Future<Output = Result<Vec<Result<SignResponse, SignError>>, SignError>> + Send + 'async_trait>>

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

Signs every message in messages, returning one result per input in input order.

fn sign_transaction<'life0, 'async_trait>( &'life0 self, message: ArchMessage, ) -> Pin<Box<dyn Future<Output = Result<RuntimeTransaction, SignError>> + Send + 'async_trait>>

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

Signs a transaction whose only required signer is this signer.

fn sign_transaction_mixed<'life0, 'life1, 'async_trait>( &'life0 self, message: ArchMessage, local_cosigners: &'life1 [UntweakedKeypair], ) -> Pin<Box<dyn Future<Output = Result<RuntimeTransaction, SignError>> + Send + 'async_trait>>

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

Signs a transaction with this signer plus local cosigner keypairs.

impl Clone for LocalSigner

fn clone(&self) -> LocalSigner

Returns a duplicate of the value.

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

Performs copy-assignment from source.
