Struct ToolCallSlot 

pub struct ToolCallSlot {
    pub id: String,
    pub name: String,
    pub signature: Option<String>,
    pub additional_params: Option<Value>,
    pub saw_arguments_delta: bool,
    pub announce_arguments: Option<Value>,
    /* private fields */
}

Wire identity of a tool call whose input is streaming, as tracked by an adapter. The slot keeps only what the wire keys by — an index — mapped to the identity the adapter established for that call.

Fields

id: String

Established provider id: updated when a later chunk carries one. Empty until the wire supplies one.

name: String

Established tool name: the last non-empty value seen.

signature: Option<String>

Provider-specific decoration carried onto the call’s end event.

additional_params: Option<Value>

Provider-specific decoration carried onto the call’s end event.

saw_arguments_delta: bool

Whether any raw argument fragment streamed for this slot. The done item’s unparseable restatement re-emits its raw bytes only when NO fragment preceded it — the buffer already holds streamed bytes, and re-emitting the restatement doubled them.

announce_arguments: Option<Value>

The payload the wire announced when it opened the call (Gemini Interactions step.start usually carries "arguments": {}, and sometimes the whole payload). Replace-if-no-deltas, never concatenated: fragments, when they arrive, ARE the arguments and the announce is ignored; only a slot that fragmented nothing falls back to what it announced.

Implementations

impl ToolCallSlot

pub fn key(&self) -> &StreamPartId

The assembly id this call’s fragments are emitted under.

pub fn observe_arguments_delta(&mut self, arguments: &str)

Record a raw argument fragment before it is forwarded to the shared accumulator.

pub fn has_substantive_arguments(&self) -> bool

Whether the wire supplied enough argument bytes to distinguish this slot from a call cut off before its first argument token.

pub fn end_event(&self, on_unparseable: UnparseableToolInput) -> ToolInputEnd

Build the end event that closes this call’s assembly in the shared accumulator, carrying the established provider id and any decoration.
