Fields

home: &'a Path

= engine.env.home; the launcher asserts equality.

bin_dir: &'a Path

~/.local/bin or %LOCALAPPDATA%\opencode-ctl; tests pass a temp dir.

running_exe: &'a Path

host: Host

probe: &'a dyn ProcessProbe

now_ms: &'a dyn Fn() -> i64

path_has: &'a dyn Fn(&str) -> bool

opencode_bin: Option<&'a Path>

The RESOLVED opencode binary for the wrapper; None = OPENCODE_NOT_FOUND for pair and attach.

version: &'a str

The front’s CARGO_PKG_VERSION: the version= line of opencode-pair.exe.source.

parent_chain: &'a dyn Fn() -> Vec<String>

server_password: Option<&'a str>

OPENCODE_SERVER_PASSWORD at launch (empty = absent).

spawn_detached: &'a dyn Fn(&mut Command) -> Result<u32>

The terminal tab: spawn and return the pid.

spawn_and_wait: &'a SpawnAndWaitFn<'a>

The controller: calls the callback with the pid right after spawn, then waits.

before_claim: Option<&'a dyn Fn()>

Test failpoint for attach: called after the record is read, before the first claim.

out: &'a mut dyn Write
