Struct wasmtime::StoreLimits

pub struct StoreLimits { /* private fields */ }

Provides limits for a Store.

This type is created with a StoreLimitsBuilder and is typically used in conjunction with Store::limiter.

This is a convenience type included to avoid needing to implement the ResourceLimiter trait if your use case fits in the static configuration that this StoreLimits provides.

Trait Implementations

impl Default for StoreLimits

fn default() -> Self

Returns the “default value” for a type.

impl ResourceLimiter for StoreLimits

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

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

fn table_growing(
    &mut self,
    _current: u32,
    desired: u32,
    _maximum: Option<u32>
) -> bool

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

fn instances(&self) -> usize

The maximum number of instances that can be created for a Store.

fn tables(&self) -> usize

The maximum number of tables that can be created for a Store.

fn memories(&self) -> usize

The maximum number of linear memories that can be created for a Store

fn memory_grow_failed(&mut self, _error: &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)

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