}

SessionMeta contains session-level data that doesn’t correspond to a specific turn.

NOTE: There used to be an instructions field here, which stored user_instructions, but we now save that on TurnContext. base_instructions stores the base instructions for the session, and should be used when there is no config override.

Fields

session_id: SessionId

id: ThreadId

forked_from_id: Option<ThreadId>

parent_thread_id: Option<ThreadId>

timestamp: String

cwd: PathBuf

originator: String

cli_version: String

source: SessionSource

thread_source: Option<ThreadSource>

Optional analytics source classification for this thread.

agent_nickname: Option<String>

Optional random unique nickname assigned to an AgentControl-spawned sub-agent.

agent_role: Option<String>

Optional role (agent_role) assigned to an AgentControl-spawned sub-agent.

agent_path: Option<String>

Optional canonical agent path assigned to an AgentControl-spawned sub-agent.

model_provider: Option<String>

base_instructions: Option<BaseInstructions>

base_instructions for the session. This should always be present when creating a new session, but may be missing for older sessions. If not present, fall back to rendering the base_instructions from ModelsManager.

dynamic_tools: Option<Vec<DynamicToolSpec>>

selected_capability_roots: Vec<SelectedCapabilityRoot>

Capability roots selected for this thread by the hosting platform.

memory_mode: Option<String>

history_mode: ThreadHistoryMode

history_base: Option<HistoryPosition>

Exclusive prefix of another paginated rollout inherited by this thread.

subagent_history_start_ordinal: Option<u64>

First rollout ordinal that belongs to this subagent’s own projected history.

Earlier rollout records are inherited model context and stay out of child turn/item projection.

multi_agent_version: Option<MultiAgentVersion>

context_window: Option<SessionContextWindow>

Initial context-window identity for consumers that tail rollout JSONL before compaction.

Trait Implementations

impl Clone for SessionMeta

fn clone(&self) -> SessionMeta

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SessionMeta

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for SessionMeta

fn default() -> SessionMeta

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SessionMeta

fn deserialize<__D>( __deserializer: __D, ) -> Result<SessionMeta, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for SessionMeta

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl Serialize for SessionMeta

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TS for SessionMeta

type WithoutGenerics = SessionMeta

If this type does not have generic parameters, then WithoutGenerics should just be Self. If the type does have generic parameters, then all generic parameters must be replaced with a dummy type, e.g ts_rs::Dummy or (). The only requirement for these dummy types is that EXPORT_TO must be None.

type OptionInnerType = SessionMeta

If the implementing type is std::option::Option<T>, then this associated type is set to T. All other implementations of TS should set this type to Self instead.

fn ident() -> String

Identifier of this type, excluding generic parameters.

fn docs() -> Option<String>

JSDoc comment to describe this type in TypeScript - when TS is derived, docs are automatically read from your doc comments or #[doc = ".."] attributes

fn name() -> String

Name of this type in TypeScript, including generic parameters

fn decl_concrete() -> String

Declaration of this type using the supplied generic arguments. The resulting TypeScript definition will not be generic. For that, see TS::decl(). If this type is not generic, then this function is equivalent to TS::decl().

fn decl() -> String

Declaration of this type, e.g. type User = { user_id: number, ... }. This function will panic if the type has no declaration.

fn inline() -> String

Formats this types definition in TypeScript, e.g { user_id: number }. This function will panic if the type cannot be inlined.

fn inline_flattened() -> String

Flatten a type declaration.
This function will panic if the type cannot be flattened.

fn visit_generics(v: &mut impl TypeVisitor)

where SessionMeta: 'static,

Iterates over all type parameters of this type.

fn output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
The returned path does not include the base directory from TS_RS_EXPORT_DIR.

fn visit_dependencies(v: &mut impl TypeVisitor)

where SessionMeta: 'static,

Iterates over all dependency of this type.

fn dependencies() -> Vec<Dependency>

where Self: 'static,

Resolves all dependencies of this type recursively.

fn export() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem. To export this type together with all of its dependencies, use TS::export_all.

fn export_all() -> Result<(), ExportError>

where Self: 'static,

Manually export this type to the filesystem, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_all_to(out_dir: impl AsRef<Path>) -> Result<(), ExportError>

where Self: 'static,

Manually export this type into the given directory, together with all of its dependencies.
To export only this type, without its dependencies, use TS::export.

fn export_to_string() -> Result<String, ExportError>

where Self: 'static,

Manually generate bindings for this type, returning a String.
This function does not format the output, even if the format feature is enabled.

fn default_output_path() -> Option<PathBuf>

Returns the output path to where T should be exported.
