0.53.0 broke semver?

[dvdplm]

I think #1688 broke semver. Updating rust-mbedtls from using bindgen@0.52.0to ``bindgen@0.53.0` I'm getting a ton of errors like:

error[E0308]: mismatched types
   --> mbedtls/src/x509/csr.rs:196:22
    |
196 |                 Some(F::call),
    |                      ^^^^^^^ expected `u64`, found `usize`
    |
    = note: expected fn pointer `unsafe extern "C" fn(_, _, u64) -> _`
                  found fn item `unsafe extern "C" fn(_, _, usize) -> _ {<F as rng::RngCallback>::call}`

Possibly the culprit is #1688?

Not sure what can be done at this time, but yeah, upgrading bindgen is harder than it could be.

It didn't. See https://semver.org/.

Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.

Yes, plus fwiw, you may want size_t_is_usize=true to restore the previous behavior.

Right, which was introduced in 0.53.0 if I’m not mistaken?
