Struct nannou::vk::InstanceBuilder

pub struct InstanceBuilder {
    pub app_info: Option<ApplicationInfo<'static>>,
    pub extensions: Option<InstanceExtensions>,
    pub layers: Vec<String>,
    pub loader: Option<FunctionPointers<Box<dyn Loader + Send + Sync>>>,
}

A builder struct that makes the process of building an instance more modular.

Fields

app_info: Option<ApplicationInfo<'static>>

extensions: Option<InstanceExtensions>

layers: Vec<String>

loader: Option<FunctionPointers<Box<dyn Loader + Send + Sync>>>

Methods

impl InstanceBuilder

pub fn new() -> Self

Begin building a vulkano instance.

pub fn app_info(self, app_info: ApplicationInfo<'static>) -> Self

Specify the application info with which the instance should be created.

pub fn extensions(self, extensions: InstanceExtensions) -> Self

Specify the exact extensions to enable for the instance.

pub fn add_extensions(self, ext: InstanceExtensions) -> Self

Add the given extensions to the set of existing extensions within the builder.

Unlike the extensions method, this does not disable pre-existing extensions.

pub fn layers<L>(self, layers: L) -> Self where
    L: IntoIterator,
    L::Item: Into<String>, 

Specify the exact layers to enable for the instance.

pub fn add_layers<L>(self, layers: L) -> Self where
    L: IntoIterator,
    L::Item: Into<String>, 

Extend the existing list of layers with the given layers.

pub fn add_loader(
    self,
    loader: FunctionPointers<Box<dyn Loader + Send + Sync>>
) -> Self

Add custom vulkan loader

pub fn build(self) -> Result<Arc<Instance>, InstanceCreationError>

Build the vulkan instance with the existing parameters.
