Struct MemoryType

pub struct MemoryType { /* private fields */ }

A Wasm memory descriptor.

Implementations

impl MemoryType

pub fn new(minimum: u32, maximum: Option<u32>) -> Self

Creates a new memory type with minimum and optional maximum pages.

Panics

• If the minimum pages exceeds the maximum pages.
• If the minimum or maximum pages are out of bounds.

pub fn new64(minimum: u64, maximum: Option<u64>) -> Self

Creates a new 64-bit memory type with minimum and optional maximum pages.

Panics

• If the minimum pages exceeds the maximum pages.
• If the minimum or maximum pages are out of bounds.

64-bit memories are part of the Wasm memory64 proposal.

pub fn builder() -> MemoryTypeBuilder

Returns a MemoryTypeBuilder to incrementally construct a MemoryType.

pub fn is_64(&self) -> bool

Returns true if this is a 64-bit MemoryType.

64-bit memories are part of the Wasm memory64 proposal.

pub fn minimum(self) -> u64

Returns the minimum pages of the memory type.

pub fn maximum(self) -> Option<u64>

Returns the maximum pages of the memory type.

Returns None if there is no limit set.

Trait Implementations

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

Formats the value using the given formatter.

impl From<MemoryType> for ExternType

fn from(memory: MemoryType) -> Self

Converts to this type from the input type.

impl PartialEq for MemoryType

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