trezoa-example-mocks 3.2.2

//! 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.
