A rust implementation of the MurmurHash3_. Both 32 bit and 128 bit versions are included. The 128
bit version is implemented with 64 bit datatypes, making it most suitable for x86_64 or other 64 bit
architectures.
----
Usage
=====
In your ``Cargo.toml``:
.. code:: toml
[dependencies]
murmurhash3 = "*"
Then you can start to use either ``murmurhash3_x86_32`` or ``murmurhash3_x64_128``:
.. code:: rust
use murmurhash3::murmurhash3_x64_128;
fn hash_value() {
let data = "test data";
let seed = 48221234;
let hash = murmurhash3_x64_128(data.as_bytes(), seed);
}
Unfortunately, there is a bug in the ``HashState`` library implementation which prevents
implementation of new ``Hasher`` implementations for use in for example ``HashMap``. Additionally,
only the 32 bit hasher can be used there since ``HashMap`` uses a 64 bit hash internally.
Tests
=====
.. code::
cargo test
Runs all tests with optimization level 3 in order to weed out potential problems with the optimizer.
