Enum ColorProfileSource 

#[non_exhaustive]
pub enum ColorProfileSource<'a> {
    Icc(&'a [u8]),
    Cicp(Cicp),
    Named(NamedProfile),
    PrimariesTransferPair {
        primaries: ColorPrimaries,
        transfer: TransferFunction,
    },
}

A source color profile — either ICC bytes, CICP parameters, a named profile, or a primaries + transfer function pair.

This unified type lets consumers pass decoded image color info directly to a CMS backend without caring whether the source had an ICC profile, CICP codes, or a well-known named profile.

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.

Icc(&'a [u8])

Raw ICC profile data.

Cicp(Cicp)

CICP parameters (a CMS can synthesize an equivalent profile).

Named(NamedProfile)

Well-known named profile.

PrimariesTransferPair

Color primaries + transfer function pair.

Covers the full ColorPrimaries × TransferFunction matrix, including combinations that don’t have a NamedProfile variant or a CICP mapping (e.g., Adobe RGB).

A CMS backend that handles this variant can avoid ICC profile parsing entirely for known primaries/transfer combinations.

Fields

primaries: ColorPrimaries

Color primaries (gamut + white point).

transfer: TransferFunction

Transfer function (EOTF encoding).

Implementations

impl<'a> ColorProfileSource<'a>

pub const fn from_primaries_transfer( primaries: ColorPrimaries, transfer: TransferFunction, ) -> ColorProfileSource<'a>

Create from primaries + transfer function.

pub const fn primaries_transfer( &self, ) -> Option<(ColorPrimaries, TransferFunction)>

Try to extract primaries + transfer, regardless of variant.

• PrimariesTransferPair — returns directly
• Named — decomposes via NamedProfile::to_primaries_transfer
• Cicp — maps via ColorPrimaries::from_cicp and TransferFunction::from_cicp
• Icc — returns None (requires profile parsing)

Trait Implementations

impl<'a> Clone for ColorProfileSource<'a>

fn clone(&self) -> ColorProfileSource<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ColorProfileSource<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for ColorProfileSource<'a>

fn eq(&self, other: &ColorProfileSource<'a>) -> 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.
