++//! Mock a struct that implements Serde traits
++//!
++//! Serde defines to popular traits that look like this:
++//! ```ignore
++//! trait Serialize {
++//! fn serialize<S: Serializer>(&self, serializer: S) -> Result<String, anyhow::Error>;
++//! }
++//! trait Deserialize {
++//! fn deserialize<D: Deserializer>(deserializer: D) -> Result<Self, anyhow::Error>;
++//! }
++//! ```
++//!
++//! Mockall can usually implement traits with generic methods. However,
++//! `serde::Serializer` isn't `'static`, and the definition of
++//! `Serialize::serialize` doesn't require `S` to be static. That's a problem,
++//! because Mockall requires that all generic methods' generic types be
++//! `'static` so that they can implement `std::any::Any`.
++//!
++//! There's no getting around that requirement. But there's still hope! You
++//! can mock a struct that implements Serde traits by manually implementing
++//! `Serialize` and `Deserialize` in terms of non-generic methods, using a
++//! surrogate object for the expectations.
