Snap for 9200392 from 0b39044a12b130d5165335162623cf4f58b7f7fb to tm-qpr2-release Change-Id: Id50023597c089551ba804d091d336aafd34b28f5
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.
