Struct wasmer::MemoryType

pub struct MemoryType {
    pub minimum: Pages,
    pub maximum: Option<Pages>,
    pub shared: bool,
}

A descriptor for a WebAssembly memory type.

Memories are described in units of pages (64KB) and represent contiguous chunks of addressable memory.

Fields

minimum: Pages

The minimum number of pages in the memory.

maximum: Option<Pages>

The maximum number of pages in the memory.

shared: bool

Whether the memory may be shared between multiple threads.

Implementations

impl MemoryType

pub fn new<IntoPages>(
    minimum: IntoPages,
    maximum: Option<IntoPages>,
    shared: bool
) -> MemoryTypewhere
    IntoPages: Into<Pages>,

Creates a new descriptor for a WebAssembly memory given the specified limits of the memory.

Trait Implementations

impl Archive for MemoryTypewhere
    Pages: Archive,
    Option<Pages>: Archive,
    bool: Archive,

type Archived = ArchivedMemoryType

The archived representation of this type.

type Resolver = MemoryTypeResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve(
    &self,
    pos: usize,
    resolver: <MemoryType as Archive>::Resolver,
    out: *mut <MemoryType as Archive>::Archived
)

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for MemoryType

fn clone(&self) -> MemoryType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryType

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

Formats the value using the given formatter.

impl<__D> Deserialize<MemoryType, __D> for <MemoryType as Archive>::Archivedwhere
    __D: Fallible + ?Sized,
    Pages: Archive,
    <Pages as Archive>::Archived: Deserialize<Pages, __D>,
    Option<Pages>: Archive,
    <Option<Pages> as Archive>::Archived: Deserialize<Option<Pages>, __D>,
    bool: Archive,
    <bool as Archive>::Archived: Deserialize<bool, __D>,

fn deserialize(
    &self,
    deserializer: &mut __D
) -> Result<MemoryType, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Display for MemoryType

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

Formats the value using the given formatter.

impl Hash for MemoryType

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

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<MemoryType> for MemoryType

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl<__S> Serialize<__S> for MemoryTypewhere
    __S: Fallible + ?Sized,
    Pages: Serialize<__S>,
    Option<Pages>: Serialize<__S>,
    bool: Serialize<__S>,

fn serialize(
    &self,
    serializer: &mut __S
) -> Result<<MemoryType as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
