Struct PhaseGuard 

pub struct PhaseGuard { /* private fields */ }

RAII guard for an arena phase. Calls begin_phase() on construction and end_phase() on drop — including during panic unwinding. Use this in place of paired begin_phase()/end_phase() calls when the phase body can panic, to avoid leaving the arena active across the unwind.

loop {
    let _guard = zk_alloc::PhaseGuard::new();
    heavy_work_that_might_panic();
    // _guard drops here on normal return AND on unwind
}

Implementations

impl PhaseGuard

pub fn new() -> Self

Begins a phase. The phase ends when the returned guard is dropped.

Trait Implementations

impl Default for PhaseGuard

fn default() -> Self

Returns the “default value” for a type.

impl Drop for PhaseGuard

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
