Expand description

Abstraction over interactive prompts so tests can inject scripted answers.

Required Methods§

Source

fn ask_string( &mut self, prompt: &str, default: Option<&str>, optional: bool, ) -> Result<String>

Ask for a free-form string.

Source

fn ask_bool(&mut self, prompt: &str, default: bool) -> Result<bool>

Ask for a boolean (y/n).

Source

fn ask_int(&mut self, prompt: &str, default: Option<i64>) -> Result<i64>

Ask for an integer.

Dyn Compatibility§

This trait is dyn compatible.

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