Struct MemoryDescriptor

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

A wasm memory descriptor.

Fields

minimum: Pages

The minimum number of allowed pages.

maximum: Option<Pages>

The maximum number of allowed pages.

shared: bool

This memory can be shared between wasm threads.

memory_type: MemoryType

The type of the memory

Implementations

impl MemoryDescriptor

pub fn new( minimum: Pages, maximum: Option<Pages>, shared: bool, ) -> Result<MemoryDescriptor, String>

Create a new memory descriptor with the given min/max pages and shared flag.

pub fn memory_type(&self) -> MemoryType

Returns the MemoryType for this descriptor.

Trait Implementations

impl BorshDeserialize for MemoryDescriptor

fn deserialize_reader<__R>(reader: &mut __R) -> Result<MemoryDescriptor, Error>

where __R: Read,

fn deserialize(buf: &mut &[u8]) -> Result<Self, Error>

Deserializes this instance from a given slice of bytes. Updates the buffer to point at the remaining bytes.

fn try_from_slice(v: &[u8]) -> Result<Self, Error>

Deserialize this instance from a slice of bytes.

fn try_from_reader<R>(reader: &mut R) -> Result<Self, Error>

where R: Read,

impl BorshSerialize for MemoryDescriptor

fn serialize<__W>(&self, writer: &mut __W) -> Result<(), Error>

where __W: Write,

impl Clone for MemoryDescriptor

fn clone(&self) -> MemoryDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MemoryDescriptor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MemoryDescriptor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&MemoryDescriptor> for ExternDescriptor

fn from(other: &MemoryDescriptor) -> ExternDescriptor

Converts to this type from the input type.

impl From<MemoryDescriptor> for ExternDescriptor

fn from(other: MemoryDescriptor) -> ExternDescriptor

Converts to this type from the input type.

impl PartialEq for MemoryDescriptor

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

impl Serialize for MemoryDescriptor

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.

impl Copy for MemoryDescriptor

impl Eq for MemoryDescriptor
