Struct bevy_reflect::EnumInfo

pub struct EnumInfo { /* private fields */ }

A container for compile-time enum info, used by TypeInfo.

Implementations

impl EnumInfo

pub fn new<TEnum: Enum + TypePath>(variants: &[VariantInfo]) -> Self

Create a new EnumInfo.

Arguments

• variants: The variants of this enum in the order they are defined

pub fn with_custom_attributes(self, custom_attributes: CustomAttributes) -> Self

Sets the custom attributes for this enum.

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>

Get a variant with the given name.

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>

Get the index of the variant with the given name.

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

Checks if a variant with the given name exists within this enum.

pub fn iter(&self) -> Iter<'_, VariantInfo>

Iterate over the variants of this enum.

pub fn variant_len(&self) -> usize

The number of variants in this enum.

pub fn type_path_table(&self) -> &TypePathTable

A representation of the type path of the value.

Provides dynamic access to all methods on TypePath.

pub fn type_path(&self) -> &'static str

The stable, full type path of the value.

Use type_path_table if you need access to the other methods on TypePath.

pub fn type_id(&self) -> TypeId

The TypeId of the enum.

pub fn is<T: Any>(&self) -> bool

Check if the given type matches the enum type.

pub fn custom_attributes(&self) -> &CustomAttributes

Returns the custom attributes for this item.

pub fn get_attribute<T: Reflect>(&self) -> Option<&T>

Gets a custom attribute by type.

For dynamically accessing an attribute, see get_attribute_by_id.

pub fn get_attribute_by_id(&self, id: TypeId) -> Option<&dyn Reflect>

Gets a custom attribute by its TypeId.

This is the dynamic equivalent of get_attribute.

pub fn has_attribute<T: Reflect>(&self) -> bool

Returns true if this item has a custom attribute of the specified type.

For dynamically checking if an attribute exists, see has_attribute_by_id.

pub fn has_attribute_by_id(&self, id: TypeId) -> bool

Returns true if this item has a custom attribute with the specified TypeId.

This is the dynamic equivalent of has_attribute

Trait Implementations

impl Clone for EnumInfo

fn clone(&self) -> EnumInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EnumInfo

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

Formats the value using the given formatter.
