What the loop asks of the world besides the network.

Required Methods

fn save_language(&mut self, lang: Lang) -> Result<(), String>

fn write_file(&mut self, path: &str, contents: &str) -> Result<(), String>

Writes a new file (never over an existing one).

fn write_secret(&mut self, path: &str, contents: &str) -> Result<(), String>

Writes a new file that only its owner can read (a token secret); never over an existing one.

fn save_profiles(&mut self, file: &ConfigFile) -> Result<(), String>

Writes the default profile and the profiles, keeping the rest of the file as it is on disk.

fn check_profile(&mut self, profile: &Profile) -> CheckResult

Tries the connection of a profile that may not be saved.

fn connect(&mut self, name: &str) -> Result<Connection, String>

What the calls of a profile of the file go through, and the address it ends up using.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
