[−][src]Function core::arch::wasm32::memory::grow
pub unsafe fn grow(mem: i32, delta: i32) -> i32
This is supported on MIPS only.
Corresponding intrinsic to wasm's memory.grow
instruction
This function, when called, will attempt to grow the default linear memory
by the specified delta
of pages. If memory is successfully grown then the
previous size of memory, in pages, is returned. If memory cannot be grown
then -1 is returned.
The argument mem
is the numerical index of which memory to return the
size of. Note that currently wasm only supports one memory, so specifying
a nonzero value will likely result in a runtime validation error of the
wasm module.
