Struct RuntimeOptions 

pub struct RuntimeOptions {
    pub heap: HeapLimits,
    pub min_heap: usize,
    pub growth: f64,
    pub stack_limit: u32,
    pub native_stack_budget: usize,
    pub native_depth_limit: u32,
}

How a runtime is configured. Default is the behavior every runtime had before the options existed.

Fields

heap: HeapLimits

The heap cap; usize::MAX bytes for none.

min_heap: usize

The reserved-bytes budget’s floor, in bytes.

growth: f64

A collection that leaves live bytes allows growth × live more to be allocated before the next: the budget is (1 + growth) × live.

stack_limit: u32

Registers the register file may hold before a call fails with InternalError: stack overflow.

native_stack_budget: usize

Bytes of host stack nested re-entries into the loop may use.

native_depth_limit: u32

Nested re-entries into the loop allowed at most (unbounded by default): for a host whose stack the byte measure cannot see, such as a WebAssembly engine’s.
