Struct FilterChainVulkan 

pub struct FilterChainVulkan { /* private fields */ }

A Vulkan filter chain.

Implementations

impl FilterChainVulkan

pub unsafe fn load_from_path<V, E>( path: impl AsRef<Path>, features: ShaderFeatures, vulkan: V, options: Option<&FilterChainOptionsVulkan>, ) -> Result<FilterChainVulkan>

where V: TryInto<VulkanObjects, Error = E>, FilterChainError: From<E>,

Load the shader preset at the given path into a filter chain.

pub unsafe fn load_from_preset<V, E>( preset: ShaderPreset, vulkan: V, options: Option<&FilterChainOptionsVulkan>, ) -> Result<FilterChainVulkan>

where V: TryInto<VulkanObjects, Error = E>, FilterChainError: From<E>,

Load a filter chain from a pre-parsed ShaderPreset.

pub unsafe fn load_from_pack<V, E>( preset: ShaderPresetPack, vulkan: V, options: Option<&FilterChainOptionsVulkan>, ) -> Result<FilterChainVulkan>

where V: TryInto<VulkanObjects, Error = E>, FilterChainError: From<E>,

Load a filter chain from a pre-parsed and loaded ShaderPresetPack.

pub unsafe fn load_from_preset_deferred<V, E>( preset: ShaderPreset, vulkan: V, cmd: CommandBuffer, options: Option<&FilterChainOptionsVulkan>, ) -> Result<FilterChainVulkan>

where V: TryInto<VulkanObjects, Error = E>, FilterChainError: From<E>,

Load a filter chain from a pre-parsed ShaderPreset, deferring and GPU-side initialization to the caller. This function therefore requires no external synchronization of the device queue.

Safety

The provided command buffer must be ready for recording and contain no prior commands. The caller is responsible for ending the command buffer and immediately submitting it to a graphics queue. The command buffer must be completely executed before calling frame.

pub unsafe fn load_from_pack_deferred<V, E>( preset: ShaderPresetPack, vulkan: V, cmd: CommandBuffer, options: Option<&FilterChainOptionsVulkan>, ) -> Result<FilterChainVulkan>

where V: TryInto<VulkanObjects, Error = E>, FilterChainError: From<E>,

Load a filter chain from a pre-parsed, loaded ShaderPresetPack, deferring and GPU-side initialization to the caller. This function therefore requires no external synchronization of the device queue.

Safety

The provided command buffer must be ready for recording and contain no prior commands. The caller is responsible for ending the command buffer and immediately submitting it to a graphics queue. The command buffer must be completely executed before calling frame.

pub unsafe fn frame( &mut self, input: &VulkanImage, viewport: &Viewport<'_, VulkanImage>, cmd: CommandBuffer, frame_count: usize, options: Option<&FrameOptionsVulkan>, ) -> Result<()>

Records shader rendering commands to the provided command buffer.

• The input image must be in the VK_SHADER_READ_ONLY_OPTIMAL layout.
• The output image must be in VK_COLOR_ATTACHMENT_OPTIMAL layout.

librashader will not create a pipeline barrier for the final pass. The output image will remain in VK_COLOR_ATTACHMENT_OPTIMAL after all shader passes. The caller must transition the output image to the final layout.
