Required Methods

fn configure_session<'a>( &'a self, bash_state: &'a mut BashState, transition: ShellSessionTransition, ) -> ShellRuntimeConfigureFuture<'a>

fn run_action<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, command: BashCommand, ) -> ShellRuntimeFuture<'a>

fn interrupt<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, ) -> ShellRuntimeUnitFuture<'a>

fn terminate_session<'a>( &'a self, thread_id: &'a str, ) -> ShellRuntimeUnitFuture<'a>

Release the runtime-owned resources for one logical session.

Provided Methods

fn attach_session<'a>( &'a self, bash_state: &'a mut BashState, ) -> ShellRuntimeConfigureFuture<'a>

Reattach an adapter to its existing session. External runtimes retain their historical mode-refresh behavior; native runtimes override this with a non-mutating fast path.

fn run_action_detailed<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, command: BashCommand, _options: ShellActionOptions, ) -> ShellRuntimeDetailedFuture<'a>

Rich adapter path used by MCP orchestration. External runtime implementations remain source-compatible through this default.

fn supports_generation_bound_actions(&self) -> ShellRuntimeBoolFuture<'_>

fn supports_generation_bound_actions_for<'a>( &'a self, _bash_state: &'a Arc<Mutex<Option<BashState>>>, ) -> ShellRuntimeBoolFuture<'a>

Session-aware capability probe. Daemon-backed runtimes override this so the answer comes from the guardian that owns this shell, not merely from the stable control process in front of it.

fn describe_session<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, ) -> ShellRuntimeStatusFuture<'a>

Describe the session without mutating it. The default inspects the in-process PTY; daemon-backed runtimes ask the guardian that owns it.

fn interrupt_generation<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, expected_generation: Option<u64>, ) -> ShellRuntimeBoolFuture<'a>

Interrupt only the exact command generation owned by a Task. The conservative default refuses generation-bound interruption.

fn interrupt_execution<'a>( &'a self, bash_state: &'a Arc<Mutex<Option<BashState>>>, expected: Option<ShellExecutionToken>, ) -> ShellRuntimeBoolFuture<'a>

Interrupt only the complete execution identity. External runtimes keep working through the generation-only conservative default.

fn cancel_pending_action<'a>( &'a self, _bash_state: &'a Arc<Mutex<Option<BashState>>>, _cancellation_key: &'a str, ) -> ShellRuntimeBoolFuture<'a>

Cancel a command that is reserved remotely but has not reached the PTY. Embedded runtimes use the in-process cancellation flag and need no additional reservation protocol.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
