Struct DispatchFormat

pub struct DispatchFormat<PosFmt, NegFmt> { /* private fields */ }

A formatter which dispatches to different formatters depending on whether the matcher is negated or not.

This type is a MatcherFormat that wraps two existing formatters, one for the positive case (we expected the matcher to match) and one for the negative case (we expected the matcher to fail). It dispatches to one of those formatters depending on whether the matcher is negated or not.

Implementations

impl<PosFmt, NegFmt> DispatchFormat<PosFmt, NegFmt>

pub fn new(pos_fmt: PosFmt, neg_fmt: NegFmt) -> Self

Create a new DispatchFormat from two existing formatters.

This accepts a formatter for the positive case and the negative case respectively.
