Enum PixelEndian 

pub enum PixelEndian {
    Big,
    Little,
}

Describes the endianness of pixel data in SER frames

Developers Note

Astonishingly, by convention most SER implementations invert this flag’s value from the official specification.

For example, Siril’s source code contains the following comment:

“For an unknown reason, several of the first programs to support SER disrespect the specification regarding the endianness flag. The specification states that a boolean value is used for the LittleEndian header, and they use it as a BigEndian header, with 0 for little-endian and 1 for big-endian. Consequently, to not break compatibility with these first implementations, later programs, like Siril and GoQat, have also decided to implement this header in opposite meaning to the specification.”

Other rust crates seem to follow this convention, and this crate does as well.

Write Self to the writer assuming big-endian byte order.

fn write_le<W>(&self, writer: &mut W) -> Result<(), Error>

where W: Write + Seek, Self::Args<'a>: for<'a> Required,

Write Self to the writer assuming little-endian byte order.

fn write_ne<W>(&self, writer: &mut W) -> Result<(), Error>

impl Clone for PixelEndian

fn clone(&self) -> PixelEndian

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PixelEndian

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

Formats the value using the given formatter.

impl Default for PixelEndian

fn default() -> Self

Returns the “default value” for a type.

impl From<&PixelEndian> for Endian

fn from(value: &PixelEndian) -> Self

Converts to this type from the input type.

impl PartialEq for PixelEndian

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