Struct ZwpPointerConstraintsV1

pub struct ZwpPointerConstraintsV1 { /* private fields */ }

Available on crate feature wayland and Linux only.

constrain the movement of a pointer

The global interface exposing pointer constraining functionality. It exposes two requests: lock_pointer for locking the pointer to its position, and confine_pointer for locking the pointer to a region.

The lock_pointer and confine_pointer requests create the objects wp_locked_pointer and wp_confined_pointer respectively, and the client can use these objects to interact with the lock.

For any surface, only one lock or confinement may be active across all wl_pointer objects of the same seat. If a lock or confinement is requested when another lock or confinement is active or requested on the same surface and with any of the wl_pointer objects of the same seat, an ‘already_constrained’ error will be raised.

See also the Request enum for this interface.

impl PartialEq<Weak<ZwpPointerConstraintsV1>> for ZwpPointerConstraintsV1

fn eq(&self, other: &Weak<ZwpPointerConstraintsV1>) -> 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.
