Struct SupercompressionScheme 

pub struct SupercompressionScheme(/* private fields */);

Supercompression applied to mip level data.

None (raw value 0) at the Header level means no supercompression — level data is ready to use directly.

Vendor-specific schemes use IDs >= 0x10000.

Implementations

impl SupercompressionScheme

pub const BasisLZ: Self

Basis Universal LZ. Level data must be transcoded, not just decompressed. Global data section contains codebooks. Level::uncompressed_byte_length will be 0.

pub const Zstandard: Self

Zstandard (zstd). Decompress each level independently.

pub const ZLIB: Self

ZLIB (deflate). Decompress each level independently.

pub const ALL: &'static [Self]

pub fn new(x: u32) -> Option<Self>

pub fn value(&self) -> u32

Trait Implementations

impl Clone for SupercompressionScheme

fn clone(&self) -> SupercompressionScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SupercompressionScheme

impl Debug for SupercompressionScheme

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

Formats the value using the given formatter.

impl Eq for SupercompressionScheme

impl Hash for SupercompressionScheme

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 SupercompressionScheme

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

This method returns an Ordering between self and other.

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

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SupercompressionScheme

fn eq(&self, other: &SupercompressionScheme) -> 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 PartialOrd for SupercompressionScheme

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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