Trait Callbacks

pub trait Callbacks {
    // Required methods
    fn prompt(&self, message: &str);
    fn request_public_string(&self, description: &str) -> Option<String>;
    fn request_passphrase(&self, description: &str) -> Option<SecretString>;
}

Callbacks that might be triggered during encryption or decryption.

Structs that implement this trait should be given directly to the individual Recipient or Identity implementations that require them.

Required Methods

fn prompt(&self, message: &str)

Shows a message to the user.

This can be used to prompt the user to take some physical action, such as inserting a hardware key.

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>

Requests a passphrase to decrypt a key.
