Struct ReadOnlyTransport 

pub struct ReadOnlyTransport { /* private fields */ }

Read-only NDJSON transport wrapping a codex subprocess.

Each line read from stdout is a single JSON object. There is no stdin writing — the prompt is passed as a CLI argument.

Implementations

impl ReadOnlyTransport

pub fn spawn( cli_path: &str, subcommand: &str, extra_args: &[String], prompt: Option<&str>, working_dir: Option<&Path>, env_vars: &[(String, String)], ) -> Result<Self>

Spawn a new codex process.

The process is launched as <cli_path> <subcommand> --json [extra_args...] [prompt]. Stdin is /dev/null — there is no send method.

Errors

Returns SdkError::ProcessSpawn if the process cannot be started.

pub async fn recv(&mut self) -> Result<Option<Value>>

Read the next NDJSON line from stdout and parse it as a JSON value.

Returns Ok(None) when stdout reaches EOF (process exited).

Errors

Returns SdkError::InvalidJson if a line is not valid JSON. Returns SdkError::Io on read failure.

pub fn interrupt(&self) -> Result<()>

Send an interrupt signal (SIGINT on Unix) to the subprocess.

pub async fn kill(&mut self) -> Result<()>

Kill the subprocess immediately (SIGKILL on Unix).

pub async fn wait_with_stderr( &mut self, ) -> Result<(Option<i32>, Option<String>)>

Wait for the subprocess to exit and return the exit code and captured stderr.

pub fn try_wait(&mut self) -> Result<Option<ExitStatus>>

Check whether the child process has exited without blocking.
