memory_id: MemoryId,
offset: WordSize,
buf_ptr: Pointer<u8>,
buf_len: WordSize
) -> Result<u32>
[src]
&mut self,
memory_id: MemoryId,
offset: WordSize,
buf_ptr: Pointer<u8>,
buf_len: WordSize
) -> Result<u32>
Get sandbox memory from the memory_id
instance at offset
into the given buffer.
fn memory_set(
&mut self,
memory_id: MemoryId,
offset: WordSize,
val_ptr: Pointer<u8>,
val_len: WordSize
) -> Result<u32>
[src]
&mut self,
memory_id: MemoryId,
offset: WordSize,
val_ptr: Pointer<u8>,
val_len: WordSize
) -> Result<u32>
Set sandbox memory from the given value.
fn memory_teardown(&mut self, memory_id: MemoryId) -> Result<()>
[src]
Delete a memory instance.
fn memory_new(&mut self, initial: u32, maximum: u32) -> Result<MemoryId>
[src]
Create a new memory instance with the given initial
size and the maximum
size.
The size is given in wasm pages.

instance_id: u32,
export_name: &str,
args: &[u8],
return_val: Pointer<u8>,
return_val_len: WordSize,
state: u32

[src]
&mut self,
instance_id: u32,
export_name: &str,
args: &[u8],
return_val: Pointer<u8>,
return_val_len: WordSize,
state: u32
) -> Result<u32>
Invoke an exported function by a name.
fn instance_teardown(&mut self, instance_id: u32) -> Result<()>
[src]
Delete a sandbox instance.
fn instance_new(
&mut self,
dispatch_thunk_id: u32,
wasm: &[u8],
raw_env_def: &[u8],
state: u32
) -> Result<u32>
[src]
&mut self,
dispatch_thunk_id: u32,
wasm: &[u8],
raw_env_def: &[u8],
state: u32
) -> Result<u32>
Create a new sandbox instance.
fn get_global_val(&self, instance_idx: u32, name: &str) -> Result<Option<Value>>
[src]
Get the value from a global with the given name
. The sandbox is determined by the
given instance_idx
instance.
Returns Some(_)
when the requested global variable could be found.
