Struct pam_client::conv_cli::Conversation

pub struct Conversation { /* fields omitted */ }

Command-line implementation of ConversationHandler

This struct is unavailable if pam-client is built without the "cli" feature.

Prompts, info and error messages will be written to STDERR, non-secret input in read from STDIN and rpassword is used to prompt the user for passwords.

Limitations

Please note that UTF-8 encoding is assumed for terminal I/O, so this handler may fail to authenticate on legacy non-UTF-8 systems when the user input contains non-ASCII characters.

Implementations

pub fn info_prefix(&self) -> &str

The prefix text written before info text

pub fn set_info_prefix(&mut self, prefix: impl Into<String>)

Updates the prefix put before info text

pub fn error_prefix(&self) -> &str
