[−]Struct mockall_examples::__mock_Foo_Foo::bang::Expectation
Expectation type for methods that return a 'static
type.
This is the type returned by the expect_*
methods.
Methods
impl Expectation
pub fn return_const<MockallOutput>(&mut self, c: MockallOutput) -> &mut Self where
MockallOutput: Clone + Into<i32> + Send + 'static,
MockallOutput: Clone + Into<i32> + Send + 'static,
Return a constant value from the Expectation
The output type must be Clone
. The compiler can't always
infer the proper type to use with this method; you will usually
need to specify it explicitly. i.e. return_const(42i32)
instead of return_const(42)
.
pub fn return_once<F>(&mut self, f: F) -> &mut Self where
F: FnOnce(i32) -> i32 + Send + 'static,
F: FnOnce(i32) -> i32 + Send + 'static,
Supply an FnOnce
closure that will provide the return value
for this Expectation. This is useful for return types that
aren't Clone
. It will be an error to call this method
multiple times.
pub fn return_once_st<F>(&mut self, f: F) -> &mut Self where
F: FnOnce(i32) -> i32 + 'static,
F: FnOnce(i32) -> i32 + 'static,
Single-threaded version of return_once
.
This is useful for return types that are neither Send
nor
Clone
.
It is a runtime error to call the mock method from a different thread than the one that originally called this method. It is also a runtime error to call the method more than once.
pub fn returning<F>(&mut self, f: F) -> &mut Self where
F: FnMut(i32) -> i32 + Send + 'static,
F: FnMut(i32) -> i32 + Send + 'static,
Supply a closure that will provide the return value for this
Expectation
. The method's arguments are passed to the closure
by value.
pub fn returning_st<F>(&mut self, f: F) -> &mut Self where
F: FnMut(i32) -> i32 + 'static,
F: FnMut(i32) -> i32 + 'static,
Single-threaded version of returning
.
Can be used when the argument or return type isn't Send
.
It is a runtime error to call the mock method from a different thread than the one that originally called this method.
pub fn in_sequence(&mut self, seq: &mut Sequence) -> &mut Self
Add this expectation to a Sequence
.
pub fn never(&mut self) -> &mut Self
Forbid this expectation from ever being called.
pub fn new() -> Self
Create a new, default, Expectation
pub fn once(&mut self) -> &mut Self
Expect this expectation to be called exactly once. Shortcut for
times(1)
.
pub fn times(&mut self, n: usize) -> &mut Self
Expect this expectation to be called exactly n
times.
pub fn times_any(&mut self) -> &mut Self
Allow this expectation to be called any number of times
This behavior is the default, but the method is provided in case the default behavior changes.
pub fn times_range(&mut self, range: Range<usize>) -> &mut Self
Allow this expectation to be called any number of times within a given range
pub fn with<p0: Predicate<i32> + Send + 'static>(&mut self, x: p0) -> &mut Self
Set matching crieteria for this Expectation.
The matching predicate can be anything implemening the
Predicate
trait. Only
one matcher can be set per Expectation
at a time.
pub fn withf<F>(&mut self, f: F) -> &mut Self where
F: Fn(&i32) -> bool + Send + 'static,
F: Fn(&i32) -> bool + Send + 'static,
Set a matching function for this Expectation.
This is equivalent to calling with
with a function
argument, like with(predicate::function(f))
.
