Struct Mismatch 

pub struct Mismatch {
    pub expected: Description,
    pub actual: String,
    pub diff: Option<String>,
}

Why a value failed a matcher: what was expected, what was found, and an optional diff between the two.

Fields

expected: Description

The matcher’s expectation, as a composable Description.

actual: String

The Debug rendering of the actual value.

diff: Option<String>

An optional pre-rendered diff between expected and actual. None when no diff is available.

pub fn new(expected: Description, actual: impl Into<String>) -> Mismatch

pub fn with_diff(self, diff: impl Into<String>) -> Mismatch
