Enum Encoding 

pub enum Encoding {
    Mono,
    MonoA,
    Palette4,
    Palette8,
    Mask8,
    RLE24,
    JP2PNG,
}

Methods of encoding an image within an icon element.

Each IconType uses a particular encoding within an ICNS file; this type enumerates those encodings.

(This type is used internally by the library, but is irrelvant to most library users; if you’re not sure whether you need to use it, you probably don’t.)

Variants

Mono

Icon element data payload is an uncompressed one bit image

MonoA

Icon element data payload is an uncompressed one bit image with a one bit mask

Palette4

Icon element data payload is an uncompressed image with a fixed 4-bit color palette

Palette8

Icon element data payload is an uncompressed image with a fixed 8-bit color palette

Mask8

Icon element data payload is an uncompressed 8-bit alpha mask.

RLE24

Icon element data payload is an RLE-compressed 24-bit RGB image.

JP2PNG

Icon element data payload is a JPEG 2000 or PNG file.

Trait Implementations

impl Clone for Encoding

fn clone(&self) -> Encoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Encoding

impl Debug for Encoding

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

Formats the value using the given formatter.

impl Eq for Encoding

impl Hash for Encoding

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 Encoding

fn eq(&self, other: &Encoding) -> 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.
