Struct DebugMemorySettings 

pub struct DebugMemorySettings {
    pub margin: u64,
    pub initialize_allocations: bool,
    pub poison_frees: bool,
}

Opt-in host-visible debug instrumentation, configured before native acquisition. Guard margins follow VMA’s coherent pooled-memory policy. Zero disables guards.

Fields

margin: u64

Trailing guard bytes, a multiple of four. Separate native allocations have no guard tail.

initialize_allocations: bool

Initialize admitted host-visible allocation bytes with VMA’s created pattern (0xDC).

poison_frees: bool

Overwrite admitted host-visible bytes with VMA’s destroyed pattern (0xEF) on release.
