mbedtls-selftest vs mbedtls vs mbedtls-platform-support

This Rust crate is a support library for the `mbedtls` crate. It contains self-test logic that exports Rust functions and defines C functions. By separating this logic into a separate crate, multiple versions of the `mbedtls` crate can coexist within a single crate. This helps to avoid link name conflict errors.

Idiomatic Rust wrapper for MbedTLS, allowing you to use MbedTLS with only safe code while being able to use such great Rust features like error handling and closures. Building on MbedTLS's focus on embedded use, this crate can be used in a no_std environment.

This Rust crate is a support library for the `mbedtls` crate, providing platform and target specific implementations of all necessary functions. By separating this logic into a separate crate, multiple versions of the mbedtls crate can coexist within a single crate.This helps to avoid link name conflict errors. The crate exports Rust functions and defines C functions to support external overrides as needed for custom implementation under various platforms or targets.
