Struct SpawnEnv 

pub struct SpawnEnv {
    pub overrides: Vec<(String, String)>,
    pub cwd: Option<String>,
}

A typed env + cwd override an embedder stamps on every child PTY. Applied by the spawn backend AFTER the inherited + fallback env, so each (key, value) here OVERRIDES whatever the backend defaulted.

Serialize/Deserialize so a tear-client can push the override across the daemon wire (Request::SetSpawnEnv) — closing the gap where the daemon-spawned child only saw the daemon’s own env, never the embedder’s capability projection (truecolor/terminfo).

Fields

overrides: Vec<(String, String)>

Env pairs that override the backend’s inherited/fallback env. Order is preserved; later duplicates win (the backend’s env vec is a positional list CommandBuilder walks in order).

cwd: Option<String>

Working directory for the child. When Some, the spawn backend also stamps PWD=<dir> so a child shell’s $PWD matches its real cwd (the cwd-handshake hygiene). None leaves the backend’s cwd untouched.

Implementations

impl SpawnEnv

pub fn none() -> Self

An empty override — the backend’s inherited + fallback env is used verbatim (the pre-seam behaviour).

pub fn from_overrides(overrides: Vec<(String, String)>) -> Self

Build from typed env pairs (the embedder’s capability projection) with no cwd override.

pub fn with_cwd(self, cwd: Option<String>) -> Self

Set the working directory the child spawns in (and the PWD the backend stamps to match it).

pub fn is_empty(&self) -> bool

Whether this override carries anything — an empty override lets the backend skip the apply pass entirely.

pub fn apply_to(&self, env: &mut Vec<(String, String)>)

Apply this override onto a backend-built env vec IN PLACE: every override key replaces an existing entry (or pushes a new one), then PWD is reconciled with the cwd — stamped when a cwd is set, removed when it is not, so a child can never inherit a stale parent PWD. This is the ONE place the apply order is defined; both the in-process and daemon backends call it.
