Struct zng_view_api :: image :: ImageId Copy item path

impl ImageId

pub const INVALID: Self = _

Dummy ID, zero.

pub const fn first() -> Self

Create the first valid ID.

pub const fn next(self) -> Self

Create the next ID.

IDs wrap around to first when the entire u32 space is used, it is never INVALID.

pub fn incr(&mut self) -> Self

Returns self and replace self with next.

pub const fn get(self) -> u32

Get the raw ID.

pub const fn from_raw(id: u32) -> Self

Create an ID using a custom value.

Note that only the documented process must generate IDs, and that it must only generate IDs using this function or the next function.

If the id is zero it will still be INVALID and handled differently by the other process, zero is never valid.
