page_size_log2()

Builder & wasmtime::MemoryType::Builder::page_size_log2 ( uint8_t  page_size_log2 )

inline

Configure the page size (in bytes) of this memory type, via its log2 value.

The default Wasm page size is 65536 (or 2**16).

With the custom-page-sizes proposal, you can configure 1-byte (or 2**0) pages by passing 0 to this method. Future extensions may enable any power-of-two page size.
