Enum Encoding 

pub enum Encoding {
    Mono,

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.

ARGB

Icon element data payload is typically an RLE-compressed 32-bit ARGB image, but may also contain 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)

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,

impl Ord for Encoding

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

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for Encoding

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Encoding

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