Fnvk::load::enumerate_instance_extension_properties

pub fn enumerate_instance_extension_properties(
    entry: &Entry,
    layer_name: Option<&CStr>,
) -> Result<Vec<ExtensionProperties>, CallError>

Enumerate instance extensions available without any layer.

Enumerate instance extensions available without any layer.

Pass layer_name = None for the implicit layer (ICD + loader). Pass a layer name to query extensions exposed by that specific layer.

Returns CallError::MissingCommand if the driver predates Vulkan 1.0 (practically impossible) or CallError::Vulkan on a driver failure.

pub fn enumerate_instance_layer_properties(
    entry: &Entry,
) -> Result<Vec<LayerProperties>, CallError>

Enumerate all implicit and explicit Vulkan layers installed on this system.

Enumerate all implicit and explicit Vulkan layers installed on this system.

Returns CallError::MissingCommand if the command is absent or CallError::Vulkan on a driver failure.

pub fn enumerate_instance_version(entry: &Entry) -> Result<u32, Result>

Query the loader API version. A Vulkan 1.0 loader has no version command.
