Struct MemoryLimit 

pub struct MemoryLimit(pub Option<usize>);

The guest’s memory cap (--memory-limit): growing past it traps, with a message that says so (the JS runner checks after each guest call, with the same message).

Trait Implementations

impl ResourceLimiter for MemoryLimit

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>

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

fn memory_grow_failed(&mut self, error: Error) -> Result<(), Error>

Notifies the resource limiter that growing a linear memory, permitted by the memory_growing method, has failed.

fn table_grow_failed(&mut self, error: Error) -> Result<(), Error>

Notifies the resource limiter that growing a linear memory, permitted by the table_growing method, has failed.

fn instances(&self) -> usize
