    Gl,
    Metal,
    Vulkan,
}

Implementations

impl Backend

pub fn which<B: Backend>() -> Self

Check which backend is it.

Trait Implementations

impl Clone for Backend

fn clone(&self) -> Backend

Returns a copy 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

Formats the value using the given formatter.

impl Display for Backend

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

Formats the value using the given formatter.

impl From<EnabledBackend> for Backend

fn from(back: EnabledBackend) -> Self

Converts to this type from the input type.

impl FromStr for Backend

type Err = ParseBackendError

The associated error which can be returned from parsing.

fn from_str(string: &str) -> Result<Self, ParseBackendError>

Parses a string s to return a value of this type.

impl Hash for Backend

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Backend

fn cmp(&self, other: &Backend) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Backend

fn partial_cmp(&self, other: &Backend) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<Backend> for EnabledBackend

type Error = NotEnabled

The type returned in the event of a conversion error.

fn try_from(back: Backend) -> Result<Self, NotEnabled>

Performs the conversion.

impl Copy for Backend

impl Eq for Backend

impl StructuralPartialEq for Backend
