Enum TypeInfo

pub enum TypeInfo {
    Struct(StructInfo),
    TupleStruct(TupleStructInfo),
    Tuple(TupleInfo),
    List(ListInfo),
    Array(ArrayInfo),
    Map(MapInfo),
    Enum(EnumInfo),
    Value(ValueInfo),
}

Compile-time type information for various reflected types.

Generally, for any given type, this value can be retrieved one of three ways:

1. Typed::type_info
2. Reflect::get_represented_type_info
3. TypeRegistry::get_type_info

Each return a static reference to TypeInfo, but they all have their own use cases. For example, if you know the type at compile time, Typed::type_info is probably the simplest. If all you have is a dyn Reflect, you’ll probably want Reflect::get_represented_type_info. Lastly, if all you have is a TypeId or type path, you will need to go through TypeRegistry::get_type_info.

You may also opt to use TypeRegistry::get_type_info in place of the other methods simply because it can be more performant. This is because those other methods may require attaining a lock on the static TypeInfo, while the registry simply checks a map.

Implementations

impl TypeInfo

pub fn type_id(&self) -> TypeId

The TypeId of the underlying type.

pub fn type_path_table(&self) -> &TypePathTable

A representation of the type path of the underlying type.

Provides dynamic access to all methods on TypePath.

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

The stable, full type path of the underlying type.

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

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

Check if the given type matches the underlying type.
