Struct ExpectationList 

Source 
pub struct ExpectationList<'e, T>(/* private fields */);
Expand description

List of expectations on a value.

Implementations§

Source§

impl<'e, T: Debug> ExpectationList<'e, T>

Source

pub fn new() -> Self

Creates a new empty list of expectations.

Source

pub fn push(&mut self, expectation: impl Expectation<T> + 'e)

Add a new expectation to the list.

Source

pub fn check(&self, value: &T) -> CheckResult

Check all expectations on the value.

Runs all expectations in order.

§Returns

CheckResult::Pass if all expectations pass, otherwise CheckResult::Fail with a formatted message. If multiple failures occur, they are concatenated with newlines.
