Struct CallbackPassphraseProvider 

pub struct CallbackPassphraseProvider { /* private fields */ }

A PassphraseProvider that delegates to a callback function.

This is useful for GUI applications and FFI bindings where the passphrase input mechanism is provided externally.

Examples

use auths_core::signing::{CallbackPassphraseProvider, PassphraseProvider};

let provider = CallbackPassphraseProvider::new(|prompt| {
    // In a real GUI, this would show a dialog
    Ok("user-entered-passphrase".to_string())
});

Implementations

impl CallbackPassphraseProvider

pub fn new<F>(callback: F) -> Self

where F: Fn(&str) -> Result<Zeroizing<String>, AgentError> + Send + Sync + 'static,

Creates a new CallbackPassphraseProvider with the given callback function.

The callback receives the prompt message and should return the passphrase entered by the user, or an error if passphrase acquisition failed.
