Methods

impl Lz77WindowSize

pub fn from_u16(size: u16) -> Self

Converts from u16 to Lz77WindowSize`.

Fractions are rounded to next upper window size. If size exceeds maximum window size, lz77::MAX_WINDOW_SIZE will be used instead.

Examples

use libflate::zlib::Lz77WindowSize;

assert_eq!(Lz77WindowSize::from_u16(15000), Lz77WindowSize::KB16);
assert_eq!(Lz77WindowSize::from_u16(16384), Lz77WindowSize::KB16);
assert_eq!(Lz77WindowSize::from_u16(16385), Lz77WindowSize::KB32);
assert_eq!(Lz77WindowSize::from_u16(40000), Lz77WindowSize::KB32);

pub fn to_u16(&self) -> u16

Converts from Lz77WindowSize to u16.

Examples

use libflate::zlib::Lz77WindowSize;

assert_eq!(Lz77WindowSize::KB16.to_u16(), 16384u16);
