Struct Source 

pub struct Source(pub u32);

Available on crate feature egui only.

Which context a texture belongs to.

Every egui context allocates its texture ids from zero, so one id names different images in different contexts. A UI drawn from several contexts — the world’s own panels plus a frame laid out in another world — therefore keys its textures by this pair rather than by the id alone, which is what keeps two contexts’ atlases apart without rewriting the ids a frame carries.

The origin of the world’s own panels is Source::LOCAL; every other publisher picks its own, and the numbers are that publisher’s to allocate.

Tuple Fields

0: u32

Implementations

impl Source

pub const LOCAL: Self

The context of the world doing the drawing.

pub const fn published(slot: usize) -> Self

The context of the world publishing into slot.

The number is the slot’s plus one, so no publisher collides with the drawing world’s own panels and each slot has a namespace of its own.
