type In = IntoIter

The type of the “actual” value passed into the matcher by expect!.

type PosOut = Vec<Out, Global>

The output type of the matcher that is passed to subsequent matchers in the chain.

type NegOut = Vec<Out, Global>

The output type of the matcher in the negative case.

type PosFail = Infallible

The failure output that is passed to the formatter.

type NegFail = Infallible
