Struct Baseline 

pub struct Baseline(/* private fields */);

The baseline protocol support.

This type determines the upper bound for the globals and global versions advertised by a State. Baselines allow new protocols and new protocol versions to be added to this crate without changing the behavior of applications using the crate.

For example, if an application turns xdg_toplevel objects into zwlr_layer_surface_v1 objects, then the application should filter out globals such as xdg_toplevel_icon_v1 that take xdg_toplevels as arguments. Or else it has to also intercept the messages to that global. Without baselines, if a new protocol were added to a new release of this crate, and if that protocol interacted with xdg_toplevels, then updating this crate could cause protocol errors.

To see the contents of a baseline, look at the source file defining the baseline.

The difference between two baselines can be seen by diffing the two files containing the baselines.

Implementations

impl Baseline

pub const V0: Self

Version 0.

pub const V1: Self

Version 1.

pub const ALL_OF_THEM: Self

This baseline always contains all protocols supported by this crate in their highest supported version.

Do not use this unless you are prototyping or in very simple proxies. Use the highest baseline version available at development time instead and switch to a higher version when you update your application.
