Struct linera_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, ) -> MemoryType

where IntoPages: Into<Pages>,

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

Trait Implementations

impl Archive for MemoryType

where 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<'de> Deserialize<'de> for MemoryType

fn deserialize<__D>( __deserializer: __D, ) -> Result<MemoryType, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<__D> Deserialize<MemoryType, __D> for <MemoryType as Archive>::Archived

where __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 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 MemoryType

where __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.

impl Serialize for MemoryType

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
