To allow for the default-tls to change to a different backend by
default, this adds a new `native-tls` optional feature. Any TLS feature
that was only available using native-tls now requires the `native-tls`
feature to be enabled.
Changed the redirect types to be from the `redirect` module:
- `reqwest::RedirectPolicy` is now `reqwest::redirect::Policy`
- `reqwest::RedirectAttempt` is now `reqwest::redirect::Attempt`
- `reqwest::RedirectAction` is now `reqwest::redirect::Action`
Changed behavior of default policy to no longer check for redirect loops
(loops should still be caught eventually by the maximum limit).
Removed the `too_many_redirects` and `loop_detected` methods from
`Action`.
Added `error` to `Action` that can be passed any error type.
Closes#717
Add several lines that explain the usage of proxies in the current
version. Introduce the familiar HTTP(S)_PROXY syntax so often seen
in http(s) clients.
Closes#685
If no proxies are configured for a client, the environment (system) will
be inspected automatically to set up proxies.
Configuring a `Proxy` on a client or calling `no_proxy` will disable the
use of the automatic system proxy.
Closes#403
- The `Error`'s kind is a now a set of variants depending on the context
of when an error could occur.
- If another error was the cause, it is now always the `source`.
Along with the `is_*` methods, this should help in understanding *when*
a certain error occurred. For example, an error setting the TLS
certificates will return a builder error, with the TLS error as the
source. This should help differentiate from a TLS error that happens
when connecting to a server.
It also makes the internal code less dependent on all the exact
dependencies that can be enabled or disabled.
