Struct BackendOptions 

pub struct BackendOptions {
    pub gl: GlBackendOptions,
    pub dx12: Dx12BackendOptions,
    pub noop: NoopBackendOptions,
}

Options that are passed to a given backend.

Part of InstanceDescriptor.

Fields

gl: GlBackendOptions

Options for the OpenGL/OpenGLES backend, Backend::Gl.

dx12: Dx12BackendOptions

Options for the DX12 backend, Backend::Dx12.

noop: NoopBackendOptions

Options for the noop backend, Backend::Noop.

Implementations

impl BackendOptions

pub const fn default() -> Self

This function is identical to Default::default() except that it is a const fn.

impl BackendOptions

pub fn from_env_or_default() -> Self

Choose backend options by calling from_env on every field.

See those methods for more information.

pub fn with_env(self) -> Self

Takes the given options, modifies them based on the environment variables, and returns the result.

This is equivalent to calling with_env on every field.

Trait Implementations

impl Clone for BackendOptions

fn clone(&self) -> BackendOptions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ConstDefaultHelper for BackendOptions

const DEFAULT: Self

impl Debug for BackendOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BackendOptions

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for BackendOptions

fn eq(&self, other: &BackendOptions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
