Struct dia_assert::Assert

pub struct Assert { /* fields omitted */ }

Use this struct with Level to assert a user action.

Methods

impl Assert

pub fn new(custom_formats: Option<(String, String)>, exit_code: i32) -> Assert

Makes new instance.

• custom_formats: currently Rust doesn't support runtime formatting. So it's impossible to provide you a simpler solution. This is a workaround: the first string will be placed before the generated-string to be displayed to the user. The second string will be placed after that. If you provide None, a pre-defined format will be used.

• exit_code: will be passed to process::exit().

pub fn try(&self, level: &Level) -> Result<(), Failed>

Tries an assert.

The function generates a string with difficulty based on level. Then asks the user to type that string.

pub fn try_n(&self, level: &Level, n: u8)

Tries n times.

This function calls try().

• If the user passed, it returns peacefully.
• For other cases (the user fails, or stdout failure...), it calls process::exit() with the exit code you provided in ::new().

pub fn try_once(&self, level: &Level)

Tries once.

This function calls try_n() with 1 passed as n.
