# Ethereum primitives
# Ethereum primitives – Deprecated
[![Build Status](https://travis-ci.org/paritytech/primitives.svg?branch=master)](https://travis-ci.org/paritytech/primitives)
This repository has moved to https://github.com/paritytech/parity-common/.
Fixed-sized integer arithmetic (ethereum-types) and bloom filter (ethbloom)
To add this crate to your project, add the following in `Cargo.toml`
```toml
[dependencies]
ethereum-types = "0.4"
ethbloom = "0.5"
```
A basic example how to use this crate:
```rust
extern crate ethereum_types;
extern crate ethbloom;
use ethereum_types::U256;
use ethbloom::{Bloom, Input};
fn main() {
let mut val: U256 = 1023.into();
for _ in 0..200 { val = val * 2u32 }
assert_eq!(
&format!("{}", val),
"1643897619276947051879427220465009342380213662639797070513307648"
);
let address = [0_u8; 32];
let mut my_bloom = Bloom::default();
assert!(!my_bloom.contains_input(Input::Raw(&address)));
my_bloom.accrue(Input::Raw(&address));
}
```
### `no_std` crates
This crate has a feature, `std`, that is enabled by default. To use this crate
in a `no_std` context, add the following to your `Cargo.toml`:
```toml
[dependencies]
ethereum-types = { version = "0.4", default-features = false }
ethbloom = { version = "0.5", default-features = false }
```
Crate `ethereum-types-serialize` was renamed to [impl-serde](https://github.com/paritytech/parity-common/tree/master/primitive-types/impls/serde).
