Struct SubprocessInvokerConfig 

pub struct SubprocessInvokerConfig { /* private fields */ }

Configuration for SubprocessCallbackInvoker.

program is the external client command (an absolute path to the client’s callback binary). args are appended on every spawn. timeout bounds the total round trip — write request, read response, child exit. A child still running at deadline is killed and the invocation fails with SubprocessInvokerError::Timeout.

Implementations

impl SubprocessInvokerConfig

pub fn new(program: impl Into<PathBuf>, timeout: Duration) -> Self

Construct a config from an explicit program path and timeout. The default timeout is intentionally not provided — the caller must pick a value that matches its lifecycle SLOs.

pub fn arg(self, arg: impl Into<OsString>) -> Self

Append a single argument. Returns self for chaining.

pub fn args<I, A>(self, args: I) -> Self

where I: IntoIterator<Item = A>, A: Into<OsString>,

Append a sequence of arguments. Returns self for chaining.

pub fn program(&self) -> &PathBuf

pub fn timeout(&self) -> Duration
