The goal is to build up independent crates for the various parts of rustc, like the trait system, type checker, name resolution, etc, that can be shared by both rustc and rust-analyzer. This library depends only on alloc and core, so Finds the difference between two instances of any data structure. It aims to combine the convenience of composition-style Object-Oriented Programming Primitives for generic lazy evaluation in Rust. This crate provides the DynVec type that acts like a vector to store any datatype. Since structures are statically typed, every field in the structure must be associated with a data type.

Macro’s. However, the data structures in this library generally run in log 64 time, meaning you have to make your data structure 64 times bigger to need one extra step, and 4096 times bigger to need two steps. and fast access to the underlying strings, A safe and convenient store for one value of each type, Thread-safe Rust bindings for the HDF5 library, This crate provides data structures and functions to deal with IPv4 CIDRs and IPv6 CIDRs, UserFacingError is an error crate that allows you to pretty print your errors and error chain for consumption by the end user.
