Struct LazyAssertion

pub struct LazyAssertion<M: LazyMatcher> { /* private fields */ }

Implementations

impl<M: LazyMatcher> LazyAssertion<M>

pub fn and<F, R>(self, op: F) -> LazyAssertion<R>

where F: FnOnce(M::Ret) -> LazyAssertion<R>, R: LazyMatcher,

Not intended for direct use.

Use must_be_ok_and / must_be_err_and / must_be_some_and instead.

pub fn or<F>(self, f: F)

where F: FnOnce(&Error),

pub fn take(self) -> M::Ret

take or panic

pub fn into_result(self) -> Result<M::Ret, Error>

Not intended for direct use in testing, but exported to help extending must.

Panics if called twice.
