Struct WasmMemory 

pub struct WasmMemory {
    pub index: u32,
    pub initial_pages: u32,
    pub max_pages: Option<u32>,
    pub shared: bool,
    pub memory64: bool,
}

WASM linear memory specification

Fields

index: u32

Memory index

initial_pages: u32

Initial size in pages (64KB each)

max_pages: Option<u32>

Maximum size in pages (if specified)

shared: bool

Whether memory is shared (requires threads proposal)

memory64: bool

#1209: whether this memory is 64-bit-INDEXED (the memory64 proposal, (memory i64 ...)) rather than the default 32-bit index type. No codegen path in this crate handles an i64 memory index — data-segment offsets are decoded i32.const-only (silently DROPPING an i64.const-offset segment) and every address-materialization path assumes a 32-bit address, so a memory64 module compiled today produces EXECUTABLE, WRONG code rather than failing to compile. This flag is consumed by refuse_memory64_module in synth-cli to turn that into a loud decline at decode time, the #1046 pattern.
