Struct wasmparser_nostd::MemArg

pub struct MemArg {
    pub align: u8,
    pub offset: u64,
    pub memory: u32,
}

Represents a memory immediate in a WebAssembly memory instruction.

Fields

align: u8

Alignment, stored as n where the actual alignment is 2^n

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.
