Use the power of the `AsRef` trait to take generic parameters for
several API functions. This makes the API more ergonomic because the
callers may pass in static `str` slices or references to owned `String`s
or even more exotic things like a `Cow`, all based on their particular
situation.
Update the tests and examples to use the most natural types they have
available.
Fixes#77. No existing code should break, as `&String` implements
`AsRef<str>` and `AsRef<Path>`
For custom AuthenticatorDelegate implementations it may be very weird to
be required to return an additional character after the code from
present_user_url.
One may find himself chasing the bug which is bad UX for the user.
Improve this behavior and therefore introduce a breaking change that
will hopefully not break existing implementations nevertheless.
When implementing AuthenticatorDelegate one might want to change the
redirect_uri to use an authorized domain or just change the way
InstalledFlow works.
Add a redirect_uri method to AuthenticatorDelegate that may be
implemented to define a custom redirect uri if needed.
Recently, commits were made to remove support for using rustls/ring
in lieu of OpenSSL to avoid having to add those as dependencies in
environments where OpenSSL already exists.
However, yup-oauth2 is being used in some environments where
*OpenSSL* doesn't exist. So, retaining the option to build
it with an openssl-free stack is key.
Note, the change to hyper-native-tls is fine and actually
unrelated, because this is often happening on Windows or
Mac enviornments, where the stack that will link to is
*not* necessarily OpenSSL either.
For example, the particular breakage that prompted this
CR is a build of yup-oauth2 on iOS. In that environment,
hyper-native-tls uses Apple's Security Framework,
but OpenSSL libraries are not actually present on all
devices/simulator environments. So a link against
a mix of Security Framework and rustls make sense,
there.
Also, update to a newer version of rustls/ring while we're at it.
This removes the need for the remaining C interfaces.
Building any rust library with openssl adds a bunch
of depends such as foreign types via ffi and pkgconfg.
You are also required to have a prebuilt openssl.
Cross building and keeping up to date should be easier
with a pure rust implementation.
This bumps rustls to 0.6.1 which bumps webpki-roots.
We need this because the current version of webpki 0.8.0
has been removed from crates.io.
I created the 0.6.x rustls for hyper 0.10 support.
In future we should upade to hyper 0.11 which is rusls 0.8.0+
