Struct OpenMetadata 

pub struct OpenMetadata(/* private fields */);

Open _meta values with typed access to final reserved keys.

Implementations

impl OpenMetadata

pub fn try_from_entries( entries: impl IntoIterator<Item = (String, Value)>, ) -> Result<Self, CommonTypeError>

Validates every key and preserves valid unknown peer entries exactly.

pub fn try_from_notification_entries( entries: impl IntoIterator<Item = (String, Value)>, ) -> Result<Self, CommonTypeError>

Validates notification-role metadata without assigning request/result semantics to otherwise schema-open reserved keys.

The final schema gives only subscriptionId a typed meaning in notification metadata. Every other syntactically valid key/value is retained exactly and remains inert.

pub fn get(&self, key: &str) -> Option<&Value>

Returns the exact retained entry for a valid unknown key.

pub fn entries(&self) -> &BTreeMap<String, Value>

Returns all retained entries without granting them authority.

pub fn protocol_version(&self) -> Result<Option<&str>, CommonTypeError>

Reads the typed protocol version, if this metadata role declares it.

pub fn client_capabilities( &self, ) -> Result<Option<&Map<String, Value>>, CommonTypeError>

Reads typed client capabilities, if present.

pub fn client_info(&self) -> Result<Option<Implementation>, CommonTypeError>

Decodes the self-reported client identity without treating it as authority.

pub fn server_info(&self) -> Result<Option<Implementation>, CommonTypeError>

Decodes the self-reported server identity from final result metadata.

Final result envelopes carry this only under io.modelcontextprotocol/serverInfo in _meta.

pub fn log_level(&self) -> Result<Option<LoggingLevel>, CommonTypeError>

Reads the exact optional logging-level metadata value.
