Struct MasonChamber 

Source
pub struct MasonChamber {
    pub bee_id: BeeId,

Expand description

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§

Source§

impl MasonChamber

Source

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.

Source

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

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

Source

pub fn release_memory(&self, bytes: u64)

Release a previously allocated memory amount.

Source

pub fn utilisation(&self) -> f64

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

Source

pub fn reset(&self)

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