[−][src]Struct surfman::ContextAttributeFlags
Various flags that control attributes of the context and/or surfaces created from that context.
These roughly correspond to: https://www.khronos.org/registry/webgl/specs/latest/1.0/#WEBGLCONTEXTATTRIBUTES
There are some extra surfman
-specific flags as well.
Implementations
impl ContextAttributeFlags
[src]
pub const ALPHA: ContextAttributeFlags
[src]
Surfaces created for this context will have an alpha channel (RGBA or BGRA; i.e. 4 channels, 32 bits per pixel, 8 bits per channel). If this is not present, surfaces will be RGBX or BGRX (i.e. 3 channels, 32 bits per pixel, 8 bits per channel).
pub const DEPTH: ContextAttributeFlags
[src]
Surfaces created for this context will have a 24-bit depth buffer.
pub const STENCIL: ContextAttributeFlags
[src]
Surfaces created for this context will have an 8-bit stencil buffer, possibly using packed depth/stencil if the GL implementation supports it.
pub const COMPATIBILITY_PROFILE: ContextAttributeFlags
[src]
The OpenGL compatibility profile will be used. If this is not present, the core profile is used.
pub const fn empty() -> ContextAttributeFlags
[src]
Returns an empty set of flags
pub const fn all() -> ContextAttributeFlags
[src]
Returns the set containing all flags.
pub const fn bits(&self) -> u8
[src]
Returns the raw value of the flags currently stored.
pub fn from_bits(bits: u8) -> Option<ContextAttributeFlags>
[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: u8) -> ContextAttributeFlags
[src]
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u8) -> ContextAttributeFlags
[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: ContextAttributeFlags) -> bool
[src]
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: ContextAttributeFlags) -> bool
[src]
Returns true
all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: ContextAttributeFlags)
[src]
Inserts the specified flags in-place.
pub fn remove(&mut self, other: ContextAttributeFlags)
[src]
Removes the specified flags in-place.
pub fn toggle(&mut self, other: ContextAttributeFlags)
[src]
Toggles the specified flags in-place.
pub fn set(&mut self, other: ContextAttributeFlags, value: bool)
[src]
Inserts or removes the specified flags depending on the passed value.
