Struct Mem 

pub struct Mem(/* private fields */);

A Wasm memory.

Implementations

impl Mem

pub fn new(store: &mut Store, type_: MemType) -> Self

Creates a new Mem with the given MemType.

Panics

If the given MemType is invalid.

pub fn type_(self, store: &Store) -> MemType

Returns the MemType of this Mem.

pub fn bytes(self, store: &Store) -> &[u8]

Returns the bytes of this Mem as a slice.

pub fn bytes_mut(self, store: &mut Store) -> &mut [u8]

Returns the bytes of this Mem as a mutable slice.

pub fn size(&self, store: &Store) -> u32

Returns the size of this Mem in number of pages.

pub fn grow(self, store: &mut Store, count: u32) -> Result<u32, MemError>

Grows this Mem by the given number of pages.

Returns the previous size of this Mem in number of pages.

Errors

If this Mem failed to grow.

Trait Implementations

impl Clone for Mem

fn clone(&self) -> Mem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mem

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

Formats the value using the given formatter.

impl From<Mem> for ExternVal

fn from(memory: Mem) -> Self

Converts to this type from the input type.

impl Hash for Mem

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 Mem

fn eq(&self, other: &Mem) -> 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.
