Enum Backend 

pub enum Backend {
    Best,
    Hardware(Api),
    Software,
    Custom(String),
}

A graphical backend.

You can override the default strategy by setting the ICED_BACKEND environment variable. If you are using the default renderer, the available options are:

• wgpu for the hardware accelerated backend.
• tiny-skia for the software-based backend.

Variants

Best

Auto-detect and choose the best available Backend.

Hardware(Api)

Hardware accelerated graphics backend with the given Api.

Software

Sofware graphics backend; quite slower than hardware-based backends, but more compatible.

Custom(String)

A custom rendering backend with the given name.

Implementations

impl Backend

pub const ALL: &'static [Backend]

All the possible known combinations of Backend.

pub fn hardware(&self) -> Option<Api>

Returns true if the Backend is Backend::Hardware.

pub fn is_software(&self) -> bool

Returns true if the Backend is Backend::Software.

pub fn matches(&self, target: &str) -> bool

Returns true if the Backend is Backend::Best or matches the given name.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Backend

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

Formats the value using the given formatter.

impl Default for Backend

fn default() -> Backend

Returns the “default value” for a type.

impl Display for Backend

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

Formats the value using the given formatter.

impl From<&str> for Backend

fn from(backend: &str) -> Backend

Converts to this type from the input type.

impl From<String> for Backend

fn from(backend: String) -> Backend

Converts to this type from the input type.

impl PartialEq for Backend

fn eq(&self, other: &Backend) -> 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.
