Struct ToolSequenceRecorder 

pub struct ToolSequenceRecorder { /* private fields */ }

Thread-safe recorder for tool call sequences.

Wrap in Arc and share across async tasks / agent hooks.

Example

let recorder = ToolSequenceRecorder::new();
recorder.record("read_file", &json!({"path": "main.rs"}));
recorder.record("write_file", &json!({"path": "out.rs"}));

let diff = recorder.diff_against(&["read_file", "write_file"]);
assert!(diff.is_exact_match());

Implementations

impl ToolSequenceRecorder

pub fn new() -> Self

Create a new, empty recorder.

pub fn record(&self, name: impl Into<String>, args: &Value)

Record a tool call. Safe to call from multiple threads / async tasks.

pub fn calls(&self) -> Vec<ToolCallRecord>

Return a snapshot of all recorded calls in insertion order.

pub fn call_names(&self) -> Vec<String>

Return only the tool names in insertion order.

pub fn diff_against(&self, expected: &[&str]) -> SequenceDiff

Diff the recorded sequence against an expected list of tool names.

pub fn reset(&self)

Clear all recorded calls.

pub fn len(&self) -> usize

Number of recorded calls.

pub fn is_empty(&self) -> bool

Returns true if no calls have been recorded.

Trait Implementations

impl Clone for ToolSequenceRecorder

fn clone(&self) -> ToolSequenceRecorder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolSequenceRecorder

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

Formats the value using the given formatter.

impl Default for ToolSequenceRecorder

fn default() -> ToolSequenceRecorder

Returns the “default value” for a type.
