Wasmtime GitHub notifications bot (Jun 22 2021 at 12:06): Wasmtime GitHub notifications bot (Jun 22 2021 at 12:06):uweigand opened PR #3016 from wasm-readdir-be to main:
This code assumes that the Dirent structure has the same memory
layout on the host (Rust code) as in wasm code. This is not true
if the host is big-endian, as wasm is always little-endian.Fixed by always byte-swapping Dirent fields to little-endian
before passing them on to wasm code.<!--

Could this assert that the size of this field is 1 so the endianness is known to not matter?
