Struct PresentMethod 

#[non_exhaustive]
pub struct PresentMethod(pub u32);

different method to set the surface fullscreen

Hints to indicate to the compositor how to deal with a conflict between the dimensions of the surface and the dimensions of the output. The compositor is free to ignore this parameter.

Tuple Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

0: u32

Implementations

impl PresentMethod

pub const Default: Self

no preference, apply default policy

pub const Center: Self

center the surface on the output

pub const Zoom: Self

scale the surface, preserving aspect ratio, to the largest size that will fit on the output

pub const ZoomCrop: Self

scale the surface, preserving aspect ratio, to fully fill the output cropping if needed

pub const Stretch: Self

scale the surface to the size of the output ignoring aspect ratio

Trait Implementations

impl Clone for PresentMethod

fn clone(&self) -> PresentMethod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PresentMethod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<PresentMethod> for u32

fn from(val: PresentMethod) -> u32

Converts to this type from the input type.

impl Hash for PresentMethod

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PresentMethod

fn cmp(&self, other: &PresentMethod) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PresentMethod

fn eq(&self, other: &PresentMethod) -> 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.

impl PartialOrd for PresentMethod

fn partial_cmp(&self, other: &PresentMethod) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<u32> for PresentMethod

type Error = ()

The type returned in the event of a conversion error.

fn try_from(val: u32) -> Result<PresentMethod, ()>

Performs the conversion.
