Struct DefaultComponentCodec 

pub struct DefaultComponentCodec<C> { /* private fields */ }

Wraps an existing VersionedStateCodec as a ComponentStateCodec without requiring a second codec implementation.

Implementations

impl<C> DefaultComponentCodec<C>

pub const fn new( schema: C, codec_id: CodecId, codec_version: CodecVersion, restartability: RestartabilityDeclaration, ) -> Self

Wraps schema with the codec identity/version and restartability declaration this component requires.

pub fn with_codec_upgrades(self, upgrades: Vec<CodecVersionUpgrade>) -> Self

Declares the directed codec-version upgrades this codec can apply.

pub const fn with_sensitivity(self, sensitivity: StateSensitivity) -> Self

Declares this component’s state sensitivity.

Trait Implementations
