Prefix Parser

A parser for numbers with a binary/SI prefix on the end.

Usage:

call prefix_parser::parse_prefixes with the prefixed number to parse.

let parsed = prefix_parser::parse_prefixes("216MiB")?;

// 226492416 == 1024^2 * 216, so 226492416 is 216MiB
assert_eq!(parsed, 226492416);

Things to note:

• If no prefix is specified, the value is just converted to a number and returned.
• Capitalization is ignored. To differentiate between SI and binary, use MB vs MiB, KB vs KiB, etc...
• If just the first letter is specified, it is assumed to be in binary format (1k is 1024, not 1000).
• All of b, bb, and bib are allowed and valid, although they just keep the number as is.
