`parse-size` is an accurate, customizable, allocation-free library for

parsing byte size into integer.

```rust

use parse_size::parse_size;

assert_eq!(parse_size("0.2 MiB"), Ok(209715));

assert_eq!(parse_size("14.2e+8"), Ok(14_2000_0000));

```

## Features

* Supports both binary and decimal based prefix up to exabytes.

* Numbers can be fractional and/or in scientific notation. `parse-size` can accurately parse the input using the full 64-bit precision.

* The unit is case-insensitive. The "B" suffix is also optional (`1 KiB` = `1 kib` = `1Ki`).

* Fractional bytes are allowed, and rounded to nearest integer (`2.5 KiB` = `2560`, `2.5B` = `3`).

* Underscores and spaces in the numbers are ignored to support digit grouping (`123_456` = `123456`).

* Conventional units (KB, GB, ...) can be configured to use the binary system.

* `#![no_std]`-capable, no dependencies, and uses no heap allocation.
