Struct xpct::matchers::combinators::CombinatorContext

pub struct CombinatorContext<T> { /* private fields */ }

A type used with CombinatorMatcher to borrow, clone, or copy the owned value.

Implementations

impl<T> CombinatorContext<T>

pub fn borrow<Borrowed: ?Sized>( &mut self ) -> CombinatorAssertion<'_, '_, T, &Borrowed>where T: Borrow<Borrowed>,

Borrow the owned value before making assertions on it.

pub fn map<'a, 'b: 'a, In>( &'b mut self, func: impl Fn(&'a T) -> In + 'b ) -> CombinatorAssertion<'a, 'b, T, In>

Map the owned value before making assertions on it.

This is useful if borrowing, cloning, or copying alone aren’t flexible enough. One case where this may be useful is calling methods like Option::as_deref.

impl<T> CombinatorContext<T>where T: Copy,

pub fn copied(&mut self) -> CombinatorAssertion<'_, '_, T, T>

Copy the owned value before making assertions on it.

impl<T> CombinatorContext<T>where T: Clone,

pub fn cloned(&mut self) -> CombinatorAssertion<'_, '_, T, T>

Clone the owned value before making assertions on it.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
