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(exit_code: i32) -> Assert

Makes new instance.

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

pub fn try_with<F, S>(&self, f: F) -> Result<(), Failed> where
    F: FnOnce() -> S,
    S: AsRef<str>, 

Tries an assert with your own string.

Sometimes you need to print your own messages and/or your verification string, instead of the pre-defined ones provided by this crate. This function can help you with that.

• Inside closure f, you can print your messages.
• Then f returns the string to be verified. You can make use of Level.rand_s() if you want to.

The function will read user input from stdin and verify it. Note that case is ignored.

pub fn try_n_with<F, S>(&self, n: u8, f: F) where
    F: Fn() -> S,
    S: AsRef<str>, 

Tries n times.

This function calls try_with().

• 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_with<F, S>(&self, f: F) where
    F: Fn() -> S,
    S: AsRef<str>, 

Tries once.

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

pub fn try<T: AsRef<Level>>(&self, level: T) -> 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<T: AsRef<Level>>(&self, level: T, 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<T: AsRef<Level>>(&self, level: T)

Tries once.

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