}
Expand description
Represents a memory immediate in a WebAssembly memory instruction.
Fields§
§align: u8
Alignment, stored as n
where the actual alignment is 2^n
max_align: u8
Maximum alignment, stored as n
where the actual alignment is 2^n
.
Note that this field is not actually read from the binary format, it
will be a constant depending on which instruction this MemArg
is a
payload for.
offset: u64
A fixed byte-offset that this memory immediate specifies.
Note that the memory64 proposal can specify a full 64-bit byte offset
while otherwise only 32-bit offsets are allowed. Once validated
memory immediates for 32-bit memories are guaranteed to be at most
u32::MAX
whereas 64-bit memories can use the full 64-bits.
memory: u32
The index of the memory this immediate points to.
Note that this points within the module’s own memory index space, and is always zero unless the multi-memory proposal of WebAssembly is enabled.
