Struct Registry 

pub struct Registry { /* private fields */ }

A registry that wraps a DocStore and provides specialized methods for managing typed entries with metadata.

Registry provides a clean abstraction for storing entries with { type, config } structure. Used for:

• _index subtree: Store type metadata in databases
• transports subtree: Transport configuration in sync

Implementations

impl Registry

pub async fn get_entry(&self, name: impl AsRef<str>) -> Result<RegistryEntry>

Get metadata for a named entry

Arguments

• name - The name of the entry to query

Returns

The entry metadata if found, or an error if not registered

pub async fn contains(&self, name: impl AsRef<str>) -> bool

Check if an entry is registered

Arguments

• name - The name of the entry to check

Returns

true if the entry is registered, false otherwise

pub async fn set_entry( &self, name: impl AsRef<str>, type_id: impl Into<String>, config: Doc, ) -> Result<()>

Register or update an entry

Arguments

• name - The name of the entry to register/update
• type_id - The type identifier (e.g., “docstore:v0”, “iroh:v0”)
• config - Type-specific configuration as a Doc

Returns

Result indicating success or failure

pub async fn list(&self) -> Result<Vec<String>>

List all registered entries

Returns

A vector of entry names that are registered

pub async fn get_subtree_settings( &self, name: impl AsRef<str>, ) -> Result<SubtreeSettings>

Get the settings for a subtree.

Returns default settings if the subtree is not registered or has no settings.

Arguments

• name - The name of the subtree

Returns

The subtree settings (default if not found or not registered)

pub async fn set_subtree_settings( &self, name: impl AsRef<str>, settings: SubtreeSettings, ) -> Result<()>

Update the settings for a registered subtree.

The subtree must already be registered (via set_entry). This method only updates the settings portion, preserving the type_id and config.

Arguments

• name - The name of the subtree
• settings - The new settings to apply

Returns

Result indicating success or failure. Returns an error if the subtree is not registered.
