Update Android.bp by running cargo_embargo am: 453281a86b am: e55f55e2f1 Original change: https://android-review.googlesource.com/c/platform/external/rust/crates/num-bigint/+/3080408 Change-Id: Id12773b96a2eef0af51d6f5ba6597d28eca3de6b Signed-off-by: Automerger Merge Worker <[email protected]>
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.
| Crate | License | Min rustc | Implementation | Features |
|---|---|---|---|---|
num-bigint | MIT/Apache-2.0 | 1.31 | pure rust | dynamic width, number theoretical functions |
awint | MIT/Apache-2.0 | 1.66 | pure rust | fixed width, heap or stack, concatenation macros |
bnum | MIT/Apache-2.0 | 1.61 | pure rust | fixed width, parity with Rust primitives including floats |
crypto-bigint | MIT/Apache-2.0 | 1.57 | pure rust | fixed width, stack only |
ibig | MIT/Apache-2.0 | 1.49 | pure rust | dynamic width, number theoretical functions |
rug | LGPL-3.0+ | 1.65 | bundles GMP via gmp-mpfr-sys | all the features of GMP, MPFR, and MPC |
