//! Mock types for use in examples.
|
|
//!
|
|
//! These represent APIs from crates that themselves depend on this crate, and
|
|
//! which are useful for illustrating the examples for APIs in this crate.
|
|
//!
|
|
//! Directly depending on these crates though would cause problematic circular
|
|
//! dependencies, so instead they are mocked out here in a way that allows
|
|
//! examples to appear to use crates that this crate must not depend on.
|
|
//!
|
|
//! Each mod here has the name of a crate, so that examples can be structured to
|
|
//! appear to import from that crate.
