pub struct InstanceCreateInfo {
    pub application_name: Option<String>,
    pub application_version: Version,
    pub enabled_extensions: InstanceExtensions,
    pub enabled_layers: Vec<String>,
    pub engine_name: Option<String>,
    pub engine_version: Version,

    pub max_api_version: Option<Version>,
    pub _ne: NonExhaustive,
}

Parameters to create a new Instance.

Fields

application_name: Option<String>

A string of your choice stating the name of your application.

The default value is None.

application_version: Version

A version number of your choice specifying the version of your application.

The default value is zero.

enabled_extensions: InstanceExtensions

The extensions to enable on the instance.

The default value is InstanceExtensions::none().

enabled_layers: Vec<String>

The layers to enable on the instance.

The default value is empty.

engine_name: Option<String>

A string of your choice stating the name of the engine used to power the application.

engine_version: Version

A version number of your choice specifying the version of the engine used to power the application.

The default value is zero.

function_pointers: Option<FunctionPointers<Box<dyn Loader>>>

Function pointers loaded from a custom loader.

You can use this if you want to load the Vulkan API explicitly, rather than using Vulkano’s default.

max_api_version: Option<Version>

The highest Vulkan API version that the application will use with the instance.

Usually, you will want to leave this at the default.

The default value is Version::HEADER_VERSION, but if the supported instance version is 1.0, then it will be 1.0.

_ne: NonExhaustive

Implementations

impl InstanceCreateInfo

pub fn application_from_cargo_toml() -> Self

Returns an InstanceCreateInfo with the application_name and application_version set from information in your crate’s Cargo.toml file.

Panics

• Panics if the required environment variables are missing, which happens if the project wasn’t built by Cargo.
