Struct MemoryLimits 

pub struct MemoryLimits { /* private fields */ }

Linear memory limit metadata.

Implementations

impl MemoryLimits

pub fn new( minimum: WasmPageCount, maximum: Option<WasmPageCount>, ) -> Result<Self, WasmMemoryError>

Creates memory limits after checking that ‘maximum >= minimum’ when present.

pub const fn with_shared(self, shared: bool) -> Self

Marks the memory as shared or unshared.

pub const fn with_shared_memory(self, shared: SharedMemory) -> Self

Marks the memory with an explicit shared-memory marker.

pub const fn minimum(&self) -> WasmPageCount

Returns the minimum page count.

pub const fn minimum_pages(&self) -> u32

Returns the minimum page count as a raw integer.

pub const fn maximum(&self) -> Option<WasmPageCount>

Returns the maximum page count when bounded.

pub const fn maximum_pages(&self) -> Option<u32>

Returns the maximum page count as a raw integer when bounded.

pub const fn shared_memory(&self) -> SharedMemory

Returns the shared-memory marker.

pub const fn is_shared(&self) -> bool

Returns ‘true’ when the memory is marked as shared.

Trait Implementations

impl Clone for MemoryLimits

fn clone(&self) -> MemoryLimits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryLimits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for MemoryLimits

fn default() -> MemoryLimits

Returns the “default value” for a type.

impl Hash for MemoryLimits

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MemoryLimits

fn eq(&self, other: &MemoryLimits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
