Struct MasonChamber 

pub struct MasonChamber {
    pub bee_id: BeeId,
    pub memory_budget: u64,
    pub memory_used: AtomicU64,
    pub scratch_dir: PathBuf,
    pub task_timeout: Duration,
}

A sealed execution chamber with hard memory budget and scratch isolation.

Fields

bee_id: BeeId

The bee that owns this chamber.

memory_budget: u64

Hard memory limit in bytes.

memory_used: AtomicU64

Current memory usage in bytes.

scratch_dir: PathBuf

Isolated scratch directory for this bee.

task_timeout: Duration

Maximum execution time per task.

Implementations

impl MasonChamber

pub fn new( bee_id: BeeId, memory_budget: u64, scratch_dir: PathBuf, task_timeout: Duration, ) -> Self

Create a new chamber with the given budget and scratch directory.

pub fn request_memory(&self, bytes: u64) -> Result<()>

Request a memory allocation. Returns an error if the budget would be exceeded.

pub fn release_memory(&self, bytes: u64)

Release a previously allocated memory amount.

pub fn utilisation(&self) -> f64

Return current memory utilisation as a fraction (0.0 to 1.0).

pub fn reset(&self)

Reset the chamber after a task completes: zero memory and clean scratch dir.
