pub struct ConstraintAdjustment { /* fields omitted */ }

constraint adjustments

The constraint adjustment value define ways the compositor will adjust the position of the surface, if the unadjusted position would result in the surface being partly constrained.

Whether a surface is considered 'constrained' is left to the compositor to determine. For example, the surface may be partly outside the compositor's defined 'work area', thus necessitating the child surface's position be adjusted until it is entirely inside the work area.

The adjustments can be combined, according to a defined precedence: 1) Flip, 2) Slide, 3) Resize.

Methods

impl ConstraintAdjustment

pub const None: ConstraintAdjustment

don't move the child surface when constrained

Don't alter the surface position even if it is constrained on some axis, for example partially outside the edge of a monitor.

pub const SlideX: ConstraintAdjustment

move along the x axis until unconstrained

Slide the surface along the x axis until it is no longer constrained.

First try to slide towards the direction of the gravity on the x axis until either the edge in the opposite direction of the gravity is unconstrained or the edge in the direction of the gravity is constrained.

Then try to slide towards the opposite direction of the gravity on the x axis until either the edge in the direction of the gravity is unconstrained or the edge in the opposite direction of the gravity is constrained.

pub const SlideY: ConstraintAdjustment

move along the y axis until unconstrained

Slide the surface along the y axis until it is no longer constrained.

First try to slide towards the direction of the gravity on the y axis until either the edge in the opposite direction of the gravity is unconstrained or the edge in the direction of the gravity is constrained.

Then try to slide towards the opposite direction of the gravity on the y axis until either the edge in the direction of the gravity is unconstrained or the edge in the opposite direction of the gravity is constrained.

pub const FlipX: ConstraintAdjustment

invert the anchor and gravity on the x axis

Invert the anchor and gravity on the x axis if the surface is constrained on the x axis. For example, if the left edge of the surface is constrained, the gravity is 'left' and the anchor is 'left', change the gravity to 'right' and the anchor to 'right'.

If the adjusted position also ends up being constrained, the resulting position of the flip_x adjustment will be the one before the adjustment.

pub const FlipY: ConstraintAdjustment

invert the anchor and gravity on the y axis

Invert the anchor and gravity on the y axis if the surface is constrained on the y axis. For example, if the bottom edge of the surface is constrained, the gravity is 'bottom' and the anchor is 'bottom', change the gravity to 'top' and the anchor to 'top'.

If the adjusted position also ends up being constrained, the resulting position of the flip_y adjustment will be the one before the adjustment.

pub const ResizeX: ConstraintAdjustment

horizontally resize the surface

Resize the surface horizontally so that it is completely unconstrained.

pub const ResizeY: ConstraintAdjustment

vertically resize the surface

Resize the surface vertically so that it is completely unconstrained.

pub const fn empty() -> ConstraintAdjustment

Returns an empty set of flags

pub const fn all() -> ConstraintAdjustment

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<ConstraintAdjustment>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> ConstraintAdjustment

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: ConstraintAdjustment) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: ConstraintAdjustment) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: ConstraintAdjustment)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: ConstraintAdjustment)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: ConstraintAdjustment)

Toggles the specified flags in-place.

pub fn set(&mut self, other: ConstraintAdjustment, value: bool)

Inserts or removes the specified flags depending on the passed value.
