Struct ExecutionGraph 

pub struct ExecutionGraph {
    pub prompt_hash: String,
    pub run_started_at: DateTime<Utc>,
    pub steps: Vec<StepNode>,
    pub tool_sequence: Vec<String>,
}

Full execution trace for one TaskAgent run.

Contains one StepNode per provider call and a flat ordered tool_sequence for easy comparison against expected sequences in behavioral tests (Phase 2 recorder).

Fields

prompt_hash: String

SHA-256 of (system prompt bytes + sorted tool name bytes), hex-encoded. Changes whenever the prompt or tool registry changes.

run_started_at: DateTime<Utc>

When the run started.

steps: Vec<StepNode>

One StepNode per provider call iteration.

tool_sequence: Vec<String>

Flat ordered list of tool names across all steps (Phase 2 recorder).

Implementations

impl ExecutionGraph

pub fn new(prompt_hash: String, run_started_at: DateTime<Utc>) -> Self

Create a new, empty graph with the given prompt hash and start time.

pub fn push_step(&mut self, iteration: u32, started_at: DateTime<Utc>) -> usize

Start a new step; returns its index for later finalization.

pub fn finalize_step( &mut self, step_idx: usize, ended_at: DateTime<Utc>, prompt_tokens: u32, completion_tokens: u32, finish_reason: Option<String>, )

Fill in token counts and finish_reason after the provider call returns.

pub fn record_tool_call(&mut self, step_idx: usize, record: ToolCallRecord)

Record a tool call and append its name to the flat sequence.
