Expand description

Represents a memory’s type.

Fields§

§memory64: bool

Whether or not this is a 64-bit memory, using i64 as an index. If this is false it’s a 32-bit memory using i32 as an index.

This is part of the memory64 proposal in WebAssembly.

§shared: bool

Whether or not this is a “shared” memory, indicating that it should be send-able across threads and the maximum field is always present for valid types.

This is part of the threads proposal in WebAssembly.

§initial: u64

Initial size of this memory, in wasm pages.

For 32-bit memories (when memory64 is false) this is guaranteed to be at most u32::MAX for valid types.

§maximum: Option<u64>

Optional maximum size of this memory, in wasm pages.

For 32-bit memories (when memory64 is false) this is guaranteed to be at most u32::MAX for valid types. This field is always present for valid wasm memories when shared is true.

Implementations§

Gets the index type for the memory.

Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
Converts to this type from the input type.
