Struct RunPaths 

pub struct RunPaths {
    pub root: PathBuf,
    pub run_id: RunId,
}

Per-run paths anchored on <root>/runs/<run-id>/.

Fields

root: PathBuf

The run’s root directory; every other path is derived from it.

run_id: RunId

The validated run id this directory belongs to. Carried explicitly so event envelopes never re-derive it from root.file_name().

Implementations

impl RunPaths

pub fn new(root: impl Into<PathBuf>, run_id: impl Into<String>) -> Result<Self>

Construct paths for root (the run directory) carrying a validated run_id. Rejects malformed ids up front so every downstream event envelope and projection is stamped with a well-formed id, and rejects a run root that is a symlink (Error::SymlinkRunDir) so a replaced run directory cannot redirect writes outside the run tree. An absent root is fine — a fresh run is created later; only an existing symlink is refused. See reject_symlink for the best-effort/TOCTOU caveat.

pub fn from_validated(root: impl Into<PathBuf>, run_id: RunId) -> Result<Self>

Construct paths from an already-validated RunId, skipping the re-parse RunPaths::new does (but not the symlink-root check — that one symlink_metadata is negligible and is the production CLI’s only construction-time guard, since this is the constructor it uses). root must be the run directory (typically run_dir’s output for this same id). Rejects a symlinked root with Error::SymlinkRunDir.

pub fn manifest(&self) -> PathBuf

Path to the run manifest (manifest.json).

pub fn events(&self) -> PathBuf

Path to the append-only event log (events.jsonl).

pub fn lock(&self) -> PathBuf

Path to the advisory flock file (.lock) guarding this run.

pub fn nodes_dir(&self) -> PathBuf

Path to the nodes/ directory holding per-node projection files.

pub fn node(&self, node_id: &NodeId) -> PathBuf

Path to a single node’s projection file (nodes/<node-id>.json).

Takes a validated NodeId, so the filename can never contain / or .. and the result can never escape nodes/.

pub fn supervisor_pid(&self) -> PathBuf

Path to the supervisor pid file (supervisor.pid).

pub fn agent_log(&self) -> PathBuf

Path to the durable capture of the agent’s tmux pane (agent.log). The supervisor tees the worker pane here via tmux pipe-pane right after spawn confirmation so a post-mortem survives teardown — the file lives in the run dir, NOT the worktree, so it persists after the tmux window and worktree are removed.

Trait Implementations

impl Clone for RunPaths

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
