Module cacheable 

Serialization trait for cached values.

This module provides the Cacheable trait which defines the serialization requirements for types that can be stored in cache backends.

Feature-Dependent Bounds

The trait has different bounds depending on enabled features:

• Default: Requires Serialize + DeserializeOwned + Send + Sync (serde)
• rkyv_format: Additionally requires rkyv traits for zero-copy deserialization

Blanket Implementation

The trait is automatically implemented for all types that satisfy the bounds, so you don’t need to implement it manually. Just derive the required traits:

#[derive(serde::Serialize, serde::Deserialize)]
#[cfg_attr(feature = "rkyv_format", derive(rkyv::Archive, rkyv::Serialize, rkyv::Deserialize))]
struct MyCachedData {
    value: String,
}
// MyCachedData automatically implements Cacheable
