Struct mockall::Sequence

pub struct Sequence { /* private fields */ }

Used to enforce that mock calls must happen in the sequence specified.

Each expectation must expect to be called a fixed number of times. Once satisfied, the next expectation in the sequence will expect to be called.

Examples

#[automock]
trait Foo {
    fn foo(&self);
    fn bar(&self) -> u32;
}
let mut seq = Sequence::new();

let mut mock0 = MockFoo::new();
let mut mock1 = MockFoo::new();

mock0.expect_foo()
    .times(1)
    .returning(|| ())
    .in_sequence(&mut seq);

mock1.expect_bar()
    .times(1)
    .returning(|| 42)
    .in_sequence(&mut seq);

mock0.foo();
mock1.bar();

It is an error to add an expectation to a Sequence if its call count is unspecified.

# use mockall::*;
#[automock]
trait Foo {
    fn foo(&self);
}
let mut seq = Sequence::new();

let mut mock = MockFoo::new();
mock.expect_foo()
    .returning(|| ())
    .in_sequence(&mut seq);  // panics!
