[][src]Struct azul_webrender_api::ImageDescriptorFlags

pub struct ImageDescriptorFlags { /* fields omitted */ }

Various flags that are part of an image descriptor.

Implementations

impl ImageDescriptorFlags[src]

pub const IS_OPAQUE: ImageDescriptorFlags[src]

Whether this image is opaque, or has an alpha channel. Avoiding blending for opaque surfaces is an important optimization.

pub const ALLOW_MIPMAPS: ImageDescriptorFlags[src]

Whether to allow the driver to automatically generate mipmaps. If images are already downscaled appropriately, mipmap generation can be wasted work, and cause performance problems on some cards/drivers.

See https://github.com/servo/webrender/pull/2555/

pub const fn empty() -> ImageDescriptorFlags[src]

Returns an empty set of flags

pub const fn all() -> ImageDescriptorFlags[src]

Returns the set containing all flags.

pub const fn bits(&self) -> u32[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<ImageDescriptorFlags>[src]

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) -> ImageDescriptorFlags[src]

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

pub const unsafe fn from_bits_unchecked(bits: u32) -> ImageDescriptorFlags[src]

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

pub const fn is_empty(&self) -> bool[src]

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool[src]

Returns true if all flags are currently set.

pub const fn intersects(&self, other: ImageDescriptorFlags) -> bool[src]

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

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

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

pub fn insert(&mut self, other: ImageDescriptorFlags)[src]

Inserts the specified flags in-place.

pub fn remove(&mut self, other: ImageDescriptorFlags)[src]

Removes the specified flags in-place.

pub fn toggle(&mut self, other: ImageDescriptorFlags)[src]

Toggles the specified flags in-place.

pub fn set(&mut self, other: ImageDescriptorFlags, value: bool)[src]

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