Struct RegistrationOptions 

pub struct RegistrationOptions<T: 'static> { /* private fields */ }

Builder for configuring per-key registration options.

Obtained via the callback in RegistryBuilder::try_register_with.

Examples

builder.register_with::<Config>("config", |opts| opts
    .version(1)
    .codec(
        |val| serde_json::to_vec(val).map_err(|e| e.to_string()),
        |bytes| serde_json::from_slice(bytes).map_err(|e| e.to_string()),
    )
);

Implementations

impl<T: 'static> RegistrationOptions<T>

pub fn version(self, v: u32) -> Self

Set the wire format version (default: 1).

pub fn local_only(self) -> Self

Mark as local-only: propagates via snapshot/attach but excluded from serialization. The type does not need Serialize/DeserializeOwned.

pub fn codec( self, encode: impl Fn(&T) -> Result<Vec<u8>, String> + Send + Sync + 'static, decode: impl Fn(&[u8]) -> Result<T, String> + Send + Sync + 'static, ) -> Self

Use a custom serialization codec instead of bincode. Both encode and decode must be provided together.
