Struct SpawnPlan 

pub struct SpawnPlan {
    pub binary: String,
    pub args: Vec<String>,
    pub env_overrides: Vec<(String, String)>,
    pub session_id: Option<String>,
}

Spawn plan returned by HarnessAdapter::plan. The burn run driver owns the actual tokio::process::Command construction; this struct is the per-adapter contribution to it.

session_id is filled in by adapters that know the session id up front (claude can mint one and inject it via --session-id so the pre-spawn stamp is final from the start). Adapters that don’t know it ahead of time leave this None and rely on the pending-stamp resolver to attach their enrichment to the freshly-discovered session in after_exit.

Fields

binary: String

args: Vec<String>

env_overrides: Vec<(String, String)>

Env vars to overlay on top of the parent process env when spawning. Keep this tight — tokio::process::Command::env_clear

• this map is the typical pattern, though Wave 2 may relax that.

session_id: Option<String>

Session id the adapter pre-allocated, when known. See struct docs for when this is Some vs None.

Implementations

impl SpawnPlan

pub fn new(binary: impl Into<String>, args: Vec<String>) -> Self

Convenience: minimal plan that just runs binary with args and inherits the parent’s env. Most adapters’ plan returns this shape directly.

Trait Implementations

Performs copy-assignment from source.

impl Debug for SpawnPlan

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

impl Default for SpawnPlan

fn default() -> SpawnPlan

Returns the “default value” for a type.
