Struct GlobalRegistry 

pub struct GlobalRegistry;

Global registry singleton.

If the global registry is used, its backing registry must be provided exactly once using export_global.

The global registry must not be used to provide the backing of itself, which would result in an infinite loop at runtime.

Implementations

impl GlobalRegistry

pub fn codec_from_config<'de, D: Deserializer<'de>>( config: D, ) -> Result<ErasedDynCodec, D::Error>

Deserialize an ErasedDynCodec from its config by looking up the codec id in the GlobalRegistry.

The config must include the id field with the [DynCodecType::codec_id].

Errors

Errors if no codec with a matching id has been registered, or if constructing the codec fails.

Trait Implementations

impl Registry for GlobalRegistry

type Error = ErasedError

Error type that may be returned during get_codec.

fn get_codec<'de, D: Deserializer<'de>>( &self, config: D, ) -> Result<ErasedDynCodec, Self::Error>

Instantiate a codec of any type from its configuration.

fn get_codec_typed<'de, T: DynCodec, D: Deserializer<'de>>( &self, config: D, ) -> Result<Option<T>, Self::Error>

Instantiate a codec with a concrete type from its configuration.
