parse-size

parse-size is an accurate, customizable, allocation-free library for parsing byte size into integer.

```rust use parsesize::parsesize;

asserteq!(parsesize("0.2 MiB"), Ok(209715)); asserteq!(parsesize("14.2e+8"), Ok(1420000000)); ```

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 (2.5B = 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.
