Required Methods
fn display_message(&self, message: &str)
fn display_message(&self, message: &str)
Shows a message to the user.

fn request_public_string(&self, description: &str) -> Option<String>
fn request_public_string(&self, description: &str) -> Option<String>
Requests non-private input from the user.
To request private inputs, use Callbacks::request_passphrase
.
fn request_passphrase(&self, description: &str) -> Option<SecretString>
fn request_passphrase(&self, description: &str) -> Option<SecretString>
Requests a passphrase to decrypt a key.
