Struct rendy_core::hal::window::CompositeAlphaMode

[+] Show declaration

pub struct CompositeAlphaMode { /* fields omitted */ }

[−] Expand description

Specifies how the alpha channel of the images should be handled during compositing.

Implementations

impl CompositeAlphaMode[−]

pub const OPAQUE: CompositeAlphaMode[−][−]

The alpha channel, if it exists, of the images is ignored in the compositing process. Instead, the image is treated as if it has a constant alpha of 1.0.

pub const PREMULTIPLIED: CompositeAlphaMode[−][−]

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are expected to already be multiplied by the alpha channel by the application.

pub const POSTMULTIPLIED: CompositeAlphaMode[−][−]

The alpha channel, if it exists, of the images is respected in the compositing process. The non-alpha channels of the image are not expected to already be multiplied by the alpha channel by the application; instead, the compositor will multiply the non-alpha channels of the image by the alpha channel during compositing.

pub const INHERIT: CompositeAlphaMode[−][−]

The way in which the presentation engine treats the alpha channel in the images is unknown to gfx-hal. Instead, the application is responsible for setting the composite alpha blending mode using native window system commands. If the application does not set the blending mode using native window system commands, then a platform-specific default will be used.

pub const fn empty() -> CompositeAlphaMode[−]

Returns an empty set of flags

pub const fn all() -> CompositeAlphaMode[−]

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<CompositeAlphaMode>[−]

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) -> CompositeAlphaMode[−]

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> CompositeAlphaMode[−]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

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: CompositeAlphaMode) -> bool[−]

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

pub const fn contains(&self, other: CompositeAlphaMode) -> bool[−]

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

pub fn insert(&mut self, other: CompositeAlphaMode)[−]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CompositeAlphaMode)[−]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CompositeAlphaMode)[−]

Toggles the specified flags in-place.

pub fn set(&mut self, other: CompositeAlphaMode, value: bool)[−]

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