Trait bdk_chain::bitcoin::psbt::GetKey

pub trait GetKey {
    type Error: Debug;

    // Required method
    fn get_key<C>(
        &self,
        key_request: KeyRequest,
        secp: &Secp256k1<C>
    ) -> Result<Option<PrivateKey>, Self::Error>
       where C: Signing;
}

Trait to get a private key from a key request, key is then used to sign an input.

Required Associated Types

type Error: Debug

An error occurred while getting the key.

Required Methods

fn get_key<C>( &self, key_request: KeyRequest, secp: &Secp256k1<C> ) -> Result<Option<PrivateKey>, Self::Error>

where C: Signing,

Attempts to get the private key for key_request.

Returns

• Some(key) if the key is found.
• None if the key was not found but no error was encountered.
• Err if an error was encountered while looking for the key.

Object Safety

This trait is not object safe.
