Struct ToolContextSeed 

pub struct ToolContextSeed {
    pub thread_id: ThreadId,
    pub turn: usize,
    pub sequence_offset: u64,
    pub metadata: HashMap<String, Value>,
}

Durable inputs needed to reconstruct a crate::tools::ToolContext.

Every field is recoverable from the task / thread record in durable storage. The server serialises this when a task is created and deserialises it when a worker starts (or restarts).

This is the stable reconstruction contract — later phases depend on its shape, so changing it requires a version bump.

Fields

thread_id: ThreadId

Thread identity for the current conversation.

turn: usize

Turn number within the thread (1-based).

sequence_offset: u64

Sequence offset for event ordering continuity across turns.

The event authority uses this to resume numbering where the previous turn left off, so events within a thread form a single monotonic sequence even across worker restarts.

metadata: HashMap<String, Value>

Arbitrary key-value metadata forwarded to the tool context.

Implementations

impl ToolContextSeed

pub fn first_turn(thread_id: ThreadId) -> ToolContextSeed

Create a seed for a fresh first turn with no prior state.

pub fn with_metadata( self, key: impl Into<String>, value: Value, ) -> ToolContextSeed

Builder-style setter for metadata.

Trait Implementations

impl Clone for ToolContextSeed

fn clone(&self) -> ToolContextSeed

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolContextSeed

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolContextSeed

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ToolContextSeed

impl PartialEq for ToolContextSeed

fn eq(&self, other: &ToolContextSeed) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ToolContextSeed

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.
