Struct Lineage 

pub struct Lineage {
    pub daemon_pid: u32,
    pub client_pid: Option<u32>,
    pub session_id: Option<String>,
}

Spawn-lineage context for a single child process.

Fields

daemon_pid: u32

client_pid: Option<u32>

session_id: Option<String>

Implementations

impl Lineage

pub fn current(client_pid: Option<u32>, session_id: Option<String>) -> Self

Build a lineage for the running daemon. client_pid and session_id are None when the spawn is not associated with a client request (e.g., daemon-internal probes).

pub fn env_for_child( &self, incoming_env: Option<&[(String, String)]>, ) -> Vec<(String, String)>

Compute the lineage env vars to overlay on a child’s env.

incoming_env is the env the child will receive. We read any existing lineage chain or originator tag from it so we can extend rather than overwrite — preserving outer ancestry the CLI inherited from a build tool wrapped by running-process.

pub fn apply_to_tokio( &self, cmd: &mut Command, incoming_env: Option<&[(String, String)]>, )

Apply the lineage to a tokio::process::Command after the caller has already populated the child’s primary env.

pub fn apply_to_sync( &self, cmd: &mut Command, incoming_env: Option<&[(String, String)]>, )

Apply the lineage to a std::process::Command after the caller has already populated the child’s primary env.
