Struct ToolCall 

#[non_exhaustive]
pub struct ToolCall {
    pub name: String,
    pub args: Value,
}

One tool call the agent made: the tool’s name and the structured args it was invoked with.

args is opaque JSON so any argument shape round-trips and the built-in expect::Expectation assertions can subset-match against it. The report keeps a display string per call (see CaseOutcome::tool_calls); the runner derives those from these structured calls via ToolCall::display, so saved JSON / the --json path / the HTML report stay shape-compatible.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

The tool/function name the agent invoked.

args: Value

The arguments the agent passed, as opaque JSON (typically an object).

Implementations

impl ToolCall

pub fn new(name: impl Into<String>, args: Value) -> Self

Build a tool call from a name and its argument JSON.

pub fn display(&self) -> String

Render the compact "name(compact-args)" form used in the report’s per-case tool_calls display strings (and the human-readable summary table). The args are the JSON value’s compact string, so set_voxel({"at":[0,1,0]}) reads back the way a debugging caller expects.
