The new mime crate has several benefits:
- Faster formatting
- Easier to use. Most common mime types are now just constants, like
`mime::TEXT_PLAIN`.
- Proper suffix support.
- Extensible without breaking backwards compatiblity. This means we can
always add new constants, but before we couldn't add new variants to the
enums.
- It's now impossible for a `Mime` to contain invalid tokens. Before,
with the `Ext(String)` variants, it was possible to create an illegal
mime.
Closes#738
BREAKING CHANGE: Most uses of `mime` will likely break. There is no more
`mime!` macro, nor a `Mime` constructor, nor `TopLevel` and `SubLevel`
enums.
Instead, in most cases, a constant exists that can now be used.
For less common mime types, they can be created by parsing a string.
The `RawStatus` types on the `Response` are now gone by default. To make
use of them, the `raw_status` feature must be enabled in `Cargo.toml`.
BREAKING CHANGE: To use `RawStatus`, you must enable the `raw_status`
crate feature.
Remove requirement when calling client::Config::connector() that the connector implements Connect.
Removing this requirement allows users to set the connector back to UseDefaultConnector. Previously,
this was not possible.
This is actually one of the biggest impacts to benchmark performances at
this point. Caching the rendering of the Date header improves "hello
world" benchmarks by around 10%.
This macro isn't used anywhere, std now has an unimplemented macro
if we want to use it, and the nightly compiler now warns that this
unused. This warning is a failure when compiling tests.
Request and Response are now visible from:
- hyper::{Request, Response}
- hyper::server::{Request, Response}
- hyper::client::{Request, Response}
They truly exist in the http module, but are re-exported to reduce the number of breaking changes.
request::new and response::new were renamed to ::from_wire to reduce confusion with Request::new
and Response::new. See issue #1126
Request now has an optional Body, because not all requests have bodies.
Use body_ref() to determine if a body exists.
Use body() to take the body, or construct one if no body exists.
Closes#1155
BREAKING CHANGE: Response::body() now consumes the response
This allows servers to check if an incoming URI is in absolute form.
Especially useful for proxies to determine if the request was meant to
be proxied or aimed directly at the proxy server.
In the spirit of Postel's law, ignore invalid cookies rather than
completely discard the entire Cookie header, which is what the current
code does, and which will lead to confusion when dealing with headers
with invalid cookies injected by proxies and intermediate apps servers.
The `Cookie` header now has 'set' and `get` methods, to treat the list of
cookies as a map.
Closes#1145
BREAKING CHANGE: The `Cookie` header is no longer a wrapper over a
`Vec<String>`. It must be accessed via its `get` and `append` methods.
This makes the `u16` in `Quality` private, since it only has a valid
range of 0-1000, and can't be enforced in public. The `q` function now
allows both `f32`s and `u16`s to construct a `Quality`.
BREAKING CHANGE: Any use of `Quality(num)` should change to `q(num)`.
