Fields

palette_index: BigEndian<u16>

Index for a CPAL palette entry.

alpha: BigEndian<F2Dot14>

Alpha value. For variation, use varIndexBase + 0.

var_index_base: BigEndian<u32>

Base index into DeltaSetIndexMap.

Implementations

impl VarColorIndex

pub fn palette_index(&self) -> u16

Index for a CPAL palette entry.

pub fn alpha(&self) -> F2Dot14

Alpha value. For variation, use varIndexBase + 0.

pub fn var_index_base(&self) -> u32

Base index into DeltaSetIndexMap.

Trait Implementations

impl Clone for VarColorIndex

fn clone(&self) -> VarColorIndex

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for VarColorIndex

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

Formats the value using the given formatter.

impl FixedSize for VarColorIndex

const RAW_BYTE_LEN: usize = 8usize

The raw size of this type, in bytes.

impl Hash for VarColorIndex

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 VarColorIndex

fn cmp(&self, other: &VarColorIndex) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for VarColorIndex

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

fn partial_cmp(&self, other: &VarColorIndex) -> 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.

impl Zeroable for VarColorIndex

fn zeroed() -> Self

Calls zeroed.
