Struct MemoryManagerConfig

pub struct MemoryManagerConfig { /* private fields */ }
Expand description

MemoryManagerConfig

Immutable bucket allocation policy for a runtime. The default remains 128 Wasm pages (8 MiB). Smaller sizes trade less rounding slack for a lower 32,768-bucket capacity and more frequent growth. This policy is separate from application allocation authorization and never grants memory access.

Explicit construction checks existing memory for an exact match before any effects. This is a same-release setting, not a migration or shrink operation.
