Struct Builder 

pub struct Builder<'a> { /* private fields */ }

Builds a Vulkan BackendContext with optional extensions and protected mode.

Implementations

impl<'a> BackendContextBuilder<'a>

pub fn new( instance: Instance, physical_device: PhysicalDevice, device: Device, (queue, queue_index): (Queue, usize), get_proc: &'a impl GetProc, max_api_version: impl Into<Option<Version>>, ) -> Self

Creates a new builder for a Vulkan backend context.

The max_api_version is applied during native context creation, before the Vulkan memory allocator is initialized.

If a version is provided, it should match the value provided in VkApplicationInfo::apiVersion when creating the VkInstance. Pass None to leave Skia’s VulkanBackendContext::fMaxAPIVersion at its default 0; Skia then queries vkEnumerateInstanceVersion() and uses that loader-reported version as the upper limit when validating Vulkan entry points and creating the memory allocator.

Skia requires Vulkan 1.1 as the minimum supported API version.

pub fn with_extensions( self, instance_extensions: &[&str], device_extensions: &[&str], ) -> Self

Sets the Vulkan instance and device extension names expected by Skia.

The provided names are copied into the builder.

pub fn with_protected_context(self, protected_context: Protected) -> Self

Configures whether the context should operate in protected mode.

pub unsafe fn build(self) -> BackendContext<'a>

Creates the Vulkan BackendContext from the configured builder state.

If Self::with_protected_context() is not called, protected mode defaults to gpu::Protected::No.

Safety

instance, physical_device, device, and queue must outlive the BackendContext returned.
