Common lifecycle operations for one native sandbox instance.

Required Associated Types

type Error: Error + 'static

The native lifecycle error type.

Required Methods

fn id(&self) -> u32

The native process or boundary identifier.

fn stdin(&mut self) -> Option<&mut dyn Write>

Returns the piped standard input stream, if requested.

fn stdout(&mut self) -> Option<&mut dyn Read>

Returns the piped standard output stream, if requested.

fn stderr(&mut self) -> Option<&mut dyn Read>

Returns the piped standard error stream, if requested.

fn try_wait(&mut self) -> Result<Option<ExitStatus>, Self::Error>

Checks for completion without waiting for the command.

fn wait(&mut self) -> Result<ExitStatus, Self::Error>

Waits for completion while enforcing the prepared timeout policy.

fn kill(&mut self) -> Result<(), Self::Error>

Terminates and confirms the complete sandbox boundary.

Provided Methods

fn take_stdin(&mut self) -> Option<Box<dyn Write + Send>>

Takes ownership of the piped standard input stream, when supported.

This is used by adapters that must perform blocking stream I/O without holding the child lifecycle lock. The default keeps existing custom backends source-compatible; such adapters expose no detachable stream through that integration path.

fn take_stdout(&mut self) -> Option<Box<dyn Read + Send>>

Takes ownership of the piped standard output stream, when supported.

fn take_stderr(&mut self) -> Option<Box<dyn Read + Send>>

Takes ownership of the piped standard error stream, when supported.

Dyn Compatibility

This trait is dyn compatible.

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