Snap for 9251420 from 3e3a2de747abc46c4364490e30b17cbe0f94e4be to mainline-conscrypt-release Change-Id: I8c2ee25a4f9d8bf50bb2a36e94c22aee95ffd5df
Big integer types for Rust, BigInt and BigUint.
Add this to your Cargo.toml:
[dependencies] num-bigint = "0.4"
The std crate feature is enabled by default, and is mandatory before Rust 1.36 and the stabilized alloc crate. If you depend on num-bigint with default-features = false, you must manually enable the std feature yourself if your compiler is not new enough.
num-bigint supports the generation of random big integers when the rand feature is enabled. To enable it include rand as
rand = "0.8" num-bigint = { version = "0.4", features = ["rand"] }
Note that you must use the version of rand that num-bigint is compatible with: 0.8.
Release notes are available in RELEASES.md.
The num-bigint crate is tested for rustc 1.31 and greater.
While num-bigint strives for good performance in pure Rust code, other crates may offer better performance with different trade-offs. The following table offers a brief comparison to a few alternatives.
