pub struct EnumInfo { /* private fields */ }
Expand description
A container for compile-time enum info, used by TypeInfo
.
Implementations§
§impl EnumInfo
impl EnumInfo
pub fn new<TEnum>(name: &'static str, variants: &[VariantInfo]) -> EnumInfowhere
TEnum: Enum,
pub fn new<TEnum>(name: &'static str, variants: &[VariantInfo]) -> EnumInfowhere TEnum: Enum,
pub fn variant_names(&self) -> &[&'static str]
pub fn variant_names(&self) -> &[&'static str]
A slice containing the names of all variants in order.
pub fn variant(&self, name: &str) -> Option<&VariantInfo>
pub fn variant(&self, name: &str) -> Option<&VariantInfo>
Get a variant with the given name.
pub fn variant_at(&self, index: usize) -> Option<&VariantInfo>
pub fn variant_at(&self, index: usize) -> Option<&VariantInfo>
Get a variant at the given index.
pub fn index_of(&self, name: &str) -> Option<usize>
pub fn index_of(&self, name: &str) -> Option<usize>
Get the index of the variant with the given name.
pub fn variant_path(&self, name: &str) -> String
pub fn variant_path(&self, name: &str) -> String
Returns the full path to the given variant.
This does not check if the given variant exists.
pub fn contains_variant(&self, name: &str) -> bool
pub fn contains_variant(&self, name: &str) -> bool
Checks if a variant with the given name exists within this enum.
pub fn iter(&self) -> Iter<'_, VariantInfo>
pub fn iter(&self) -> Iter<'_, VariantInfo>
Iterate over the variants of this enum.
pub fn variant_len(&self) -> usize
pub fn variant_len(&self) -> usize
The number of variants in this enum.

fn as_bind_group_shader_type(&self, _images: &RenderAssets<Image>) -> U
Return the

. When used in AsBindGroup
derives, it is safe to assume that all images in self
exist.§impl<T> Downcast for Twhere

Convert
Box<dyn Trait>
(where Trait: Downcast

. Box<dyn Any>
can
then be further downcast
into Box<ConcreteType>
where ConcreteType
implements Trait

Convert
Rc<Trait>
(where Trait: Downcast
) to Rc<Any>
. Rc<Any>
can then be
further downcast
into Rc<ConcreteType>
where ConcreteType
implements Trait
.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait
