Expand description

WebAssembly-style heap (linear memory) configuration for Cranelift.

Fields§

§base: u32

Base global value (pointer to start of heap).

§min_size: u64

Minimum heap size in bytes.

§max_size: Option<u64>

Maximum heap size (None = unlimited).

§page_size: u64

Page size (typically 65536 for Wasm).

§needs_bounds_check: bool

Whether bounds checking is needed.

§guard_size: u64

Guard size in bytes (0 = no guard pages).

Source

pub fn static_4gib() -> Self
