Struct xpct::format::MismatchFormat

pub struct MismatchFormat<Actual, Expected> { /* private fields */ }

A formatter for Mismatch values.

Examples

let format: MismatchFormat<String, String> = MismatchFormat::new(
    "to equal",
    "to not equal",
);

let format: MismatchFormat<u32, u32> = MismatchFormat::new(
    "to be greater than or equal to",
    "to not be greater than or equal to",
);

Implementations

impl<Actual, Expected> MismatchFormat<Actual, Expected>

pub fn new(pos_msg: impl Into<String>, neg_msg: impl Into<String>) -> Self

Create a new MismatchFormat.

This accepts two error messages: the one to use in the positive case (when we were expecting the matcher to succeed) and the one to use in the negative case (when we were expecting the matcher to fail).
