[−][src]Trait wasmer_vm::Table
Trait for implementing the interface of a Wasm table.
Required methods
pub fn style(&self) -> &TableStyle
[src]
Returns the style for this Table.
pub fn ty(&self) -> &TableType
[src]
Returns the type for this Table.
pub fn size(&self) -> u32
[src]
Returns the number of allocated elements.
pub fn grow(&self, delta: u32) -> Option<u32>
[src]
Grow table by the specified amount of elements.
Returns None
if table can't be grown by the specified amount
of elements, otherwise returns the previous size of the table.
pub fn get(&self, index: u32) -> Option<VMCallerCheckedAnyfunc>
[src]
Get reference to the specified element.
Returns None
if the index is out of bounds.
pub fn set(&self, index: u32, func: VMCallerCheckedAnyfunc) -> Result<(), Trap>
[src]
pub fn vmtable(&self) -> NonNull<VMTableDefinition>
[src]
Return a VMTableDefinition
for exposing the table to compiled wasm code.
Provided methods
pub fn copy(
&self,
src_table: &dyn Table,
dst_index: u32,
src_index: u32,
len: u32
) -> Result<(), Trap>
[src]
&self,
src_table: &dyn Table,
dst_index: u32,
src_index: u32,
len: u32
) -> Result<(), Trap>
Copy len
elements from src_table[src_index..]
into dst_table[dst_index..]
.
Errors
Returns an error if the range is out of bounds of either the source or destination tables.
