parse-size
parse-size
is an accurate, customizable, allocation-free library for
parsing byte size into integer.
use parse_size;
assert_eq!;
assert_eq!;
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.
