Struct MatchResult 

pub struct MatchResult {
    pub matched: bool,
    pub failure: Option<Mismatch>,
}

The structured outcome of Matcher::check.

Invariant

matched and failure always disagree: matched == failure.is_none(). Construct values through MatchResult::pass and MatchResult::fail rather than building the struct literal, so the invariant cannot be broken.

Fields

matched: bool

Whether the value met the expectation.

failure: Option<Mismatch>

The mismatch detail, present exactly when matched is false.

Implementations

impl MatchResult

pub fn pass() -> MatchResult

The value met the expectation.

pub fn fail(mismatch: Mismatch) -> MatchResult

The value did not meet the expectation; mismatch explains why.
