cfg-if • 1.0.0A macro to ergonomically define an item depending on a large number of #[cfg]
parameters. Structured like an if-else chain, the first matching branch is the
item that gets emitted.
proc-macro2 • 1.0.92A substitute implementation of the compiler's `proc_macro` API to decouple token-based libraries from the procedural macro use case.
rand_core • 0.6.4Core random number generator traits and tools for implementation.

rustc_version • 0.4.1A library for querying the version of a installed rustc compiler

scopeguard • 1.2.0A RAII scope guard that will run a given closure when it goes out of scope,
even if the code between panics (assuming unwinding panic).
Defines the macros `defer!`, `defer_on_unwind!`, `defer_on_success!` as
shorthands for guards with one of the implemented strategies.

serde_bare • 0.5.0An implementation of the BARE (https://baremessages.org) encoding format.
stable_deref_trait • 1.2.0An unsafe marker trait for types like Box and Rc that dereference to a stable address even when moved, and hence can be used with libraries such as owning_ref and rental.
zeroize • 1.8.1Securely clear secrets from memory with a simple trait built on
stable Rust primitives which guarantee memory is zeroed using an
operation will not be 'optimized away' by the compiler.
Uses a portable pure Rust implementation that works everywhere,
even WASM!
