Known compression methods.

See TIFF compression tags for reference.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Compression

pub fn from_u16(val: u16) -> Option<Self>

Construct from a u16 value, returning None if the value is not a known tag.

pub fn from_u16_exhaustive(val: u16) -> Self

Construct from a u16 value, storing Unknown if the value is not a known tag.

pub fn to_u16(self) -> u16

Convert to a u16 value.

Trait Implementations

impl Clone for Compression

fn clone(&self) -> Compression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Compression

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

Formats the value using the given formatter.

impl Hash for Compression

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 PartialEq for Compression

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for Compression

impl Eq for Compression

impl StructuralPartialEq for Compression
