Struct ContextId 

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

Implementations

impl ContextId

pub fn try_new(value: impl Into<String>) -> Result<Self, IdValidationError>

pub fn new(value: impl Into<String>) -> Self

pub fn as_str(&self) -> &str

impl ContextId

pub fn generate() -> Self

pub fn derived_from_gateway_conversation(gw: &GatewayConversationId) -> Self

Mint a deterministic ContextId from a GatewayConversationId.

Same gateway-conversation id always produces the same ContextId, so the gateway boundary can satisfy the “every conversation has a UUID ContextId” data-integrity invariant without trusting the upstream LLM client’s x-context-id header (which carries client-specific non-UUID identifiers).

pub fn derived_from_messaging(platform: &str, org: &str, channel: &str) -> Self

Mint a deterministic ContextId for a chat-platform conversation.

The same (platform, org, channel) triple — e.g. ("slack", workspace_id, channel_id) or ("teams", tenant_id, conversation_id) — always produces the same ContextId, so the messaging dispatch boundary satisfies the “every conversation has a UUID ContextId” invariant without a channel→context mapping table.

pub fn derived_from_session(session_id: &SessionId) -> Self

Mint a deterministic ContextId from a SessionId.

Same session always produces the same ContextId, so session-scoped boundaries with no conversation of their own (anonymous sessions, hook-triggered inference such as session summaries, header fallbacks) satisfy the “every AI request belongs to exactly one real context” invariant without a session→context mapping table.

pub fn derived_from_evaluation_run(run_id: &EvalRunId) -> Self

Mint a deterministic ContextId from an evaluation run id.

Same run always produces the same ContextId, so every judge and replay request of one evaluation run lands in one context.

pub fn derived_from_cli_probe(server_name: &str) -> Self

Mint a deterministic ContextId for a CLI probe of an MCP server.

Same server name always produces the same ContextId, so repeated diagnostic probes of one server share one context.

pub fn derived_from_mcp_validation(service_name: &str) -> Self

Mint a deterministic ContextId for MCP service validation.

Same service name always produces the same ContextId, so repeated validation passes of one service share one context.

pub fn derived_from_task(task_id: &TaskId) -> Self

Mint a deterministic ContextId from a TaskId.

Fallback for task-scoped boundaries when the task’s real context row cannot be resolved; same task always produces the same ContextId.

pub fn legacy() -> Self

The fixed context that absorbs pre-invariant historical rows.

Rows written before context ids became mandatory were backfilled to this constant; read paths that meet an unparseable stored id also resolve here rather than fabricating a fresh id.
