pub struct NamespaceEngineBuilder<S> { /* private fields */ }Expand description
Builder for NamespaceEngine.
The builder keeps construction explicit: choose a namespace, choose the writer identity, then build the engine.
Implementations§
Source§impl<S: ObjectStore> NamespaceEngineBuilder<S>
impl<S: ObjectStore> NamespaceEngineBuilder<S>
Sourcepub fn namespace_id(self, namespace_id: NamespaceId) -> Self
pub fn namespace_id(self, namespace_id: NamespaceId) -> Self
Sets the namespace this engine will operate on.
Sourcepub fn writer_id(self, writer_id: impl Into<String>) -> Self
pub fn writer_id(self, writer_id: impl Into<String>) -> Self
Sets the writer identity used for epoch acquisition and commits.
Sourcepub fn build(self) -> Result<NamespaceEngine<S>, NamespaceEngineBuildError>
pub fn build(self) -> Result<NamespaceEngine<S>, NamespaceEngineBuildError>
Builds a mutating engine after required fields are present.
Sourcepub fn build_reader(
self,
) -> Result<NamespaceEngine<S>, NamespaceEngineBuildError>
pub fn build_reader( self, ) -> Result<NamespaceEngine<S>, NamespaceEngineBuildError>
Builds a read-only engine: no writer identity at all.
Only the namespace is required. Any writer identity set on the builder is dropped — a read-only engine carries none by definition.
