Implementations

impl Registry

pub fn register<T: 'static, C: DeserializeOwned + TryFrom<Url, Error = Box<dyn Error + Send + Sync>> + Into<T>>( &mut self, type_name: &'static str, )

Registers a mapping from type tag to a concrete type into the registry.

The type parameters are very important: After calling register::<Box<dyn FooTrait>, FooStruct>("footype"), when a user deserializes into an input with the type tag “myblobservicetype” into a Box<dyn FooTrait>, it will first call the Deserialize imple of FooStruct and then convert it into a Box<dyn FooTrait> using From::from.

Trait Implementations

impl Default for Registry

fn default() -> Registry

Returns the “default value” for a type.
