pub struct ExecutionContext { /* private fields */ }
Expand description

An ExecutionContext tracks how Matchers are chained together. There is a single public method called chain that when used to chain input from one matcher to another will allow tracking the flow of data across composable matchers.

Implementations§

source§

impl ExecutionContext

source

pub fn evaluate<M, I>(matcher: &mut M, input: &I) -> bool
where M: Matcher<I> + ?Sized, I: Debug + ?Sized,

Evaluate the given matcher with the provided input.

source

pub fn chain<M, I>(&mut self, matcher: &mut M, input: &I) -> bool
where M: Matcher<I> + ?Sized, I: Debug + ?Sized,

Invoke the provided matcher with the provided input. This is equivalent to invoking matcher.matches(input), but allows tracking the execution flow to provide better diagnostics about why a request did or did not match a composed set of matchers.
