thousands

Provides a trait, Separable, for formatting numbers with separators between the digits. Typically this will be used to add commas or spaces every three digits from the right, but can be configured via a SeparatorPolicy.

Usage

It’s on crates.io, so you can add

toml [dependencies] thousands = "0.1.0"

to your Cargo.toml.

This crate supports Rust version 1.22 and newer.

Examples

The simplest way to use the library is with trait Separable’s method separate_with_commas method, which does what it sounds like:

```rust use thousands::Separable;

println!("x is {}", x.separatewithcommas()); ```

There are also methods separate_with_spaces and separate_with_dots, in case your culture uses those separators.

However, it's also possible to pass a policy for different behavior:

```rust use thousands::{Separable, SeparatorPolicy, digits};

let policy = SeparatorPolicy { separator: ',', groups: &[3, 2], digits: digits::ASCII_DECIMAL, };

asserteq!( 1234567890.separateby_policy(policy), "1,23,45,67,890" ); ```
