Implementations

impl cp_layer_renderer_configuration_error_code

pub const missing_configuration: Self

An error that indicates the system didn’t find a default layer renderer configuration.

pub const unsupported_color_format: Self

An error that indicates the layer doesn’t support the current pixel format for color textures.

Compare the value the cp_layer_renderer_configuration_get_color_format function returns and make sure it matches one of the values the cp_layer_renderer_capabilities_supported_color_format function returns.

pub const unsupported_color_usage: Self

An error that indicates the layer doesn’t support the current texture usage for color textures.

Compare the value the cp_layer_renderer_configuration_get_color_usage function returns and make sure it has at least MTLTextureUsageShaderRead and does not contain MTLTextureUsageShaderAtomic or MTLTextureUsageShaderWrite

pub const unsupported_depth_format: Self

An error that indicates the layer doesn’t support the current pixel format for depth textures.

Compare the value the cp_layer_renderer_configuration_get_depth_format function returns and make sure it matches one of the values the cp_layer_renderer_capabilities_supported_depth_format function returns.

pub const unsupported_depth_usage: Self

An error that indicates the layer doesn’t support the current texture usage for depth textures.

Compare the value the cp_layer_renderer_configuration_get_depth_usage function returns and make sure it has at least MTLTextureUsageShaderRead and does not contain MTLTextureUsageShaderAtomic

pub const variable_rasterization_rate_is_not_supported: Self

An error that indicates foveation is enabled but not supported.

Disable foveation in your layer’s configuration.

pub const temporal_anti_aliasing_not_supported: Self

An error that occurs when you try to enable temporal anti-aliasing but the current configuration parameters don’t support it.

pub const not_enough_frames_requested: Self

An error that indicates not enough frames are available for rendering.

pub const too_many_frames_requested: Self

An error that indicates the system requested too many frames for rendering.

pub const unsupported_forward_depth_range: Self

An error that indicates the depth range values aren’t in reverse-z order.

When you call the cp_drawable_set_depth_range function, make sure the first value in your depth_range vector contains the value for the far plane. In addition, make sure the distance to the far plane is greater than the distance to the near plane.

pub const layout_not_supported: Self

An error that indicates the configuration’s current layout value is invalid.

Specify a supported layout value using the cp_layer_renderer_configuration_set_layout function. Get a list of supported layouts from the cp_layer_renderer_capabilities_supported_layout function.

pub const unsupported_near_plane_distance: Self

An error that indicates the near plane of the client is smaller than the supported value.

pub const unsupported_tracking_areas_format: Self

An error that indicates the layer doesn’t support the current pixel format for tracking areas textures.

Compare the value the cp_layer_renderer_configuration_get_tracking_areas_format function returns and make sure it matches one of the values the cp_layer_renderer_capabilities_supported_tracking_areas_format function returns.

pub const unsupported_tracking_areas_usage: Self

An error that indicates the layer doesn’t support the current texture usage for tracking areas textures.

Compare the value the cp_layer_renderer_configuration_get_tracking_areas_usage function returns and make sure it has at least MTLTextureUsageShaderRead and does not contain MTLTextureUsageShaderAtomic

pub const unsupported_drawable_render_context_stencil_format: Self

An error that indicates the layer doesn’t support the current pixel format for stencil texture.

Compare the value the cp_layer_renderer_configuration_get_drawable_render_context_stencil_format function returns and make sure it matches one of the values the cp_layer_renderer_capabilities_drawable_render_context_supported_stencil_format function returns.

pub const unsupported_render_quality: Self

An error that indicates the configuration’s render quality is unsupported. This could be because foveation is disabled or the quality is outside of the valid range of [0, 1], the error userInfo will contain additional information.

Trait Implementations

impl Clone for cp_layer_renderer_configuration_error_code

fn clone(&self) -> cp_layer_renderer_configuration_error_code

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for cp_layer_renderer_configuration_error_code

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

Formats the value using the given formatter.

impl Encode for cp_layer_renderer_configuration_error_code

const ENCODING: Encoding = CFIndex::ENCODING

The Objective-C type-encoding for this type.

impl Hash for cp_layer_renderer_configuration_error_code

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 cp_layer_renderer_configuration_error_code

fn cmp(&self, other: &cp_layer_renderer_configuration_error_code) -> 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 cp_layer_renderer_configuration_error_code

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