Provides facilities to construct big unsigned integer types which use no allocations (stack-based, fixed bit length).
If you want to use a predefined U128
, U256
or U512
type, take a look at the primitive-types
or ethereum-types
crate.
The focus on the provided big unsigned integer types is performance and cross-platform availability. Support a very similar API as the built-in primitive integer types.
In your Cargo.toml
paste
uint = "0.8"
Import the macro
use uint::construct_uint;
If you're using pre-edition Rust in your main file
#[macro_use]
extern crate uint;
Construct your own big unsigned integer type as follows.
// U1024 with 1024 bits consisting of 16 x 64-bit words
construct_uint! {
pub struct U1024(16);
}

std
: Use Rust's standard library.
byteorder/std
, rustc-hex/std
quickcheck
: Enable quickcheck-style property testing
cargo test --release --features=quickcheck
.arbitrary
: Allow for creation of an uint
object from random unstructured input for use with fuzzers that use the arbitrary
crate.
