Configuration flags for the Writer.

Implementations

impl WriterFlags

pub const ADJUST_COORDINATE_SPACE: WriterFlags = _

Flip output Y and extend Z from (0, 1) to (-1, 1).

pub const TEXTURE_SHADOW_LOD: WriterFlags = _

Supports GL_EXT_texture_shadow_lod on the host, which provides additional functions on shadows and arrays of shadows.

pub const DRAW_PARAMETERS: WriterFlags = _

Supports ARB_shader_draw_parameters on the host, which provides support for gl_BaseInstanceARB, gl_BaseVertexARB, and gl_DrawIDARB.

pub const INCLUDE_UNUSED_ITEMS: WriterFlags = _

Include unused global variables, constants and functions. By default the output will exclude global variables that are not used in the specified entrypoint (including indirect use), all constant declarations, and functions that use excluded global variables.

pub const FORCE_POINT_SIZE: WriterFlags = _

Emit PointSize output builtin to vertex shaders, which is required for drawing with PointList topology.

https://registry.khronos.org/OpenGL/specs/es/3.2/GLSL_ES_Specification_3.20.html#built-in-language-variables The variable gl_PointSize is intended for a shader to write the size of the point to be rasterized. It is measured in pixels. If gl_PointSize is not written to, its value is undefined in subsequent pipe stages.

impl WriterFlags

pub const fn empty() -> WriterFlags

Get a flags value with all bits unset.

pub const fn all() -> WriterFlags

Convert from a bits value.

This method will return None if any unknown bits are set.

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

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> WriterFlags

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<WriterFlags>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

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

The bitwise exclusive-or (^) of the bits in two flags values.

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

Call insert when value is true or remove when value is false.

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: WriterFlags) -> WriterFlags

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: WriterFlags) -> WriterFlags

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> WriterFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl WriterFlags

pub const fn iter(&self) -> Iter<WriterFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<WriterFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
