Struct ClaudeCodeRuntimeBackend 

pub struct ClaudeCodeRuntimeBackend { /* private fields */ }

Claude Code live-runtime backend using bidirectional stream-json print mode with supercode registered as the CLI’s permission handler.

It can create/resume sessions, cancel the running turn through the stream-json control channel, and answer the permission requests the CLI raises while a tool call is blocked.

Implementations

impl ClaudeCodeRuntimeBackend

pub fn new() -> Self

Use claude from PATH in bidirectional stream-json mode, with supercode registered as the permission handler.

pub fn launch(&self) -> &RuntimeLaunch

The command prefix this backend launches: what the registry publishes as default_launch, so a caller that hands the published launch back (the orchestrator does) gets stream-json mode and not the interactive TUI blocked on a pipe.

pub fn with_launch(launch: RuntimeLaunch) -> Self

Use an explicit Claude Code stream-json command prefix.

pub fn with_permission_timeout(self, timeout: Duration) -> Self

Override how long an unanswered permission request is held before this adapter denies it on the caller’s behalf.

See [CLAUDE_PERMISSION_RESPONSE_TIMEOUT] for the default and what it was measured against.

Trait Implementations

impl Clone for ClaudeCodeRuntimeBackend

fn clone(&self) -> ClaudeCodeRuntimeBackend

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClaudeCodeRuntimeBackend

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ClaudeCodeRuntimeBackend

fn default() -> Self

Returns the “default value” for a type.

impl RuntimeBackend for ClaudeCodeRuntimeBackend

fn harness(&self) -> HarnessId

Harness implemented by this backend.

fn capabilities(&self) -> RuntimeCapabilities

Honest mechanical capability report.

fn start<'life0, 'async_trait>( &'life0 self, request: RuntimeStartRequest, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn RuntimeConnection>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Create a fresh harness-native session.

fn attach<'life0, 'async_trait>( &'life0 self, request: RuntimeAttachRequest, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn RuntimeConnection>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Resume a persisted harness-native session through a new protocol connection. This does not imply joining the process that originally wrote the session.

fn attach_existing<'life0, 'async_trait>( &'life0 self, _request: RuntimeAttachRequest, ) -> Pin<Box<dyn Future<Output = Result<Box<dyn RuntimeConnection>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Join an already-running harness process or server. Most stock harnesses cannot do this; adapters must opt in rather than silently treating a persisted resume as a live attach.
