pub struct MemoryInstance { /* fields omitted */ }

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Linear memory instance.

Methods

impl MemoryInstance

fn new(memory_type: &MemoryType) -> Result<Arc<Self>, Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Create new linear memory instance.

fn limits(&self) -> &ResizableLimits

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Return linear memory limits.

fn size(&self) -> u32

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Return linear memory size (in pages).

fn get(&self, offset: u32, size: usize) -> Result<Vec<u8>, Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Get data at given offset.

fn get_into(&self, offset: u32, target: &mut [u8]) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Write memory slice into another slice

fn set(&self, offset: u32, value: &[u8]) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Set data at given offset.

fn grow(&self, pages: u32) -> Result<u32, Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Increases the size of the linear memory by given number of pages. Returns -1 if allocation fails or previous memory size, if succeeds.

fn copy(
    &self,
    src_offset: usize,
    dst_offset: usize,
    len: usize
) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Copy memory region. Semantically equivalent to memmove.

fn copy_nonoverlapping(
    &self,
    src_offset: usize,
    dst_offset: usize,
    len: usize
) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Copy memory region, non-overlapping version. Semantically equivalent to memcpy, but returns Error if source overlaping with destination.

fn clear(&self, offset: usize, new_val: u8, len: usize) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Clear memory region with a specified value. Semantically equivalent to memset.

fn zero(&self, offset: usize, len: usize) -> Result<(), Error>

Deprecated since 0.23

: Use wasmi crate to interpret wasm

Zero memory region
