Struct TensorWasmResourceLimiter 

pub struct TensorWasmResourceLimiter { /* private fields */ }

Per-store ResourceLimiter that caps linear-memory growth at the engine-configured max_memory_bytes.

One instance is attached to each Store via Store::limiter. Constructing it is cheap (a single usize plus the cached limit). The engine_max field is duplicated from crate::engine::EngineConfig::max_memory_bytes so the limiter does not need to re-borrow the engine during the hot memory.grow path.

Implementations

impl TensorWasmResourceLimiter

pub fn new(engine_max: usize) -> Self

Construct a limiter that denies any growth past engine_max bytes.

impl ResourceLimiter for TensorWasmResourceLimiter

fn memory_growing( &mut self, _current: usize, desired: usize, maximum: Option<usize>, ) -> Result<bool>

Notifies the resource limiter that an instance’s linear memory has been requested to grow.

fn table_growing( &mut self, _current: usize, desired: usize, maximum: Option<usize>, ) -> Result<bool>
