Implementations

impl Lz77WindowSize

fn from_u4(compression_info: u8) -> Option<Self>

fn as_u4(&self) -> u8

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);

Trait Implementations

impl Clone for Lz77WindowSize

fn clone(&self) -> Lz77WindowSize

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Lz77WindowSize

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for Lz77WindowSize

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Lz77WindowSize

fn cmp(&self, other: &Lz77WindowSize) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<Lz77WindowSize> for Lz77WindowSize

fn eq(&self, other: &Lz77WindowSize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<Lz77WindowSize> for Lz77WindowSize

fn partial_cmp(&self, other: &Lz77WindowSize) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
