Struct ImageIcon 

pub struct ImageIcon<'a> {
    pub descriptor_number: u8,
    pub last_descriptor_number: u8,
    pub icon_id: u8,
    pub body: ImageIconBody<'a>,
}

image_icon body (Table 145). One descriptor instance; a full icon spans descriptor_number 0..=last_descriptor_number, reassembled by the caller.

Icon transport mode: Table 146 (0 = data bytes, 1 = URL, 2-3 = reserved). Coordinate system: Table 147 (0 = 720×576, 1 = 1280×720, 2 = 1920×1080, 3-6 = reserved, 7 = user defined).

Fields

descriptor_number: u8

descriptor_number (4 bits) — [7:4] of byte 0.

last_descriptor_number: u8

last_descriptor_number (4 bits) — [3:0] of byte 0.

icon_id: u8

icon_id (3 bits) — [2:0] of byte 1.

body: ImageIconBody<'a>

First-segment metadata vs. continuation payload (keyed by descriptor_number == 0).

Trait Implementations

impl<'a> Clone for ImageIcon<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ImageIcon<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for ImageIcon<'a>

impl<'a> ExtensionBodyDef<'a> for ImageIcon<'a>

const TAG_EXTENSION: u8 = 0x00

The descriptor_tag_extension value this body is selected by.

const NAME: &'static str = "IMAGE_ICON"

SCREAMING_SNAKE diagnostic name, suffix-free.

impl<'a> Parse<'a> for ImageIcon<'a>

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(sel: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl<'a> PartialEq for ImageIcon<'a>

fn eq(&self, other: &ImageIcon<'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.

impl<'a> Serialize for ImageIcon<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for ImageIcon<'_>

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn to_bytes(&self) -> Vec<u8>

where Self::Error: Debug,

Convenience: allocate a Vec and serialise into it.

impl<'a> StructuralPartialEq for ImageIcon<'a>

impl<'a> Yokeable<'a> for ImageIcon<'static>

type Output = ImageIcon<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.
