Struct WindowIcon 

pub struct WindowIcon {
    pub rgba: Vec<u8>,
    pub width: u32,
    pub height: u32,
}

Window icon as raw RGBA8 bytes (4 bytes per pixel, row-major, top-left origin).

Fields

rgba: Vec<u8>

width: u32

height: u32

Implementations

impl WindowIcon

pub fn from_rgba(rgba: Vec<u8>, width: u32, height: u32) -> Self

Construct an icon from a row-major RGBA8 buffer.

The buffer must contain exactly width * height * 4 bytes. The app-level manager validates this when converting to the platform icon and logs + drops the icon on mismatch — the window still opens, just without a custom icon.

pub fn expected_len(&self) -> usize

Expected buffer size in bytes for width × height RGBA8.

pub fn is_valid(&self) -> bool

true when rgba.len() matches width × height × 4.
