How to define usize type in a .wit file. If instead of usize, I type in u64 it works. But want to know if there is a type of max unsigned integer that matches with usize.
get-size: func() -> result<usize, type-error>;
Error
0: failed to resolve directory while parsing WIT for path [./wit]
1: failed to parse package: ./wit
2: name `usize` is not defined
--> ./wit/a.wit:52:42

52 | get-size: func() -> result<usize, type-error>;

Reset to default 1From the wasm-bindgen docs:
Note: Wasm is currently a 32-bit architecture, so isize and usize are 32-bit integers and "fit" into a JavaScript Number.
So you can use a u32 in place of usize.
