Struct RegistryMetadata

pub struct RegistryMetadata {
    pub preferred_protocol: Option<String>,
    pub protocol_configs: HashMap<String, Map<String, Value>>,
    /* private fields */
}

Fields

preferred_protocol: Option<String>

The registry’s preferred protocol.

protocol_configs: HashMap<String, Map<String, Value>>

Protocol-specific configuration.

Implementations

impl RegistryMetadata

pub fn preferred_protocol(&self) -> Option<&str>

Returns the registry’s preferred protocol.

The preferred protocol is:

• the preferredProtocol metadata field, if given
• the protocol configuration key, if only one configuration is given
• the protocol backward-compatible aliases configuration, if only one configuration is given

pub fn configured_protocols(&self) -> impl Iterator<Item = Cow<'_, str>>

Returns an iterator of protocols configured by the registry.

pub fn protocol_config<T: DeserializeOwned>( &self, protocol: &str, ) -> Result<Option<T>, Error>

Deserializes protocol config for the given protocol.

Returns Ok(None) if no configuration is available for the given protocol. Returns Err if configuration is available for the given protocol but deserialization fails.
