Crate transmog_versions

Multi-version/Multi-format support for Transmog.

This crate is early in development and experimental. A low-level API has been designed and is demonstrated in these examples:

• switching-serializers.rs: Demonstrates switching between serialization formats.
• versioned-serde.rs: Demonstrates switching between major versions of structures.

A high-level procedural macro is being designed to wrap the low-level API.

• pub use transmog;

Structs

Traits

• ConstVersioned

Functions

• decode

• unwrap_version

• wrap
  Wrap data with a version header for versioned, if needed.
• write_header
  Write a version header for versioned, if needed, to write.
