Struct SandboxScope 

pub struct SandboxScope { /* private fields */ }

RAII scope for sandbox lifecycle management.

Creates sandboxes on demand via ensure(), destroys them on drop. This ensures sandboxes are always cleaned up, even on error paths. If sandboxes are disabled, all operations are no-ops.

Implementations

impl SandboxScope

pub fn new(sandbox: Sandbox, ctx: RunContext) -> Self

Create a new scope with no sandboxes.

Use ensure() to create sandboxes when needed.

pub fn ensure(&mut self, n: usize) -> Result<()>

Ensure sandboxes 0..n exist.

Creates any missing sandboxes in parallel. If sandboxes are disabled or n <= current count, this is a no-op.

On error or interrupt, newly created sandboxes are rolled back but previously existing sandboxes remain (they’ll be cleaned up on drop).

pub fn sandbox(&self) -> &Sandbox

Access the underlying sandbox for operations.

pub fn enabled(&self) -> bool

Return whether sandboxes are enabled.

pub fn shutdown(&self) -> &Arc<AtomicBool>

Access the shutdown flag.

Trait Implementations

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

Formats the value using the given formatter.

impl Drop for SandboxScope

fn drop(&mut self)

Executes the destructor for this type.
