The spec says the header can be either a `*`, `null` or an URL.
Improve docs of header.
BREAKING CHANGE: Add variant to Access-Control-Allow-Origin enum
Parses protocols into a name and a value part matching the RFC.
An enum contains all registered or known protocols, but contains
an extension variant.
Closes#480
BREAKING CHANGE: Upgrade header Protocol changed.
A single value header value can't be "", so `from_one_raw_str()` now
returns `None` on empty values. This makes custom checks in headers
obsolete.
BREAKING CHANGE: `from_one_raw_str()` returns `None` on empty values.
That way, third-parties can keep using the `header!` macro, which
now requires the `test_header!` macro as well.
Considering the `header!` macro is exported and part of the public
API, it was not desired to prevent it's usage in any way.
In empty list header values ``, or list header values with empty items `foo, , bar`,
the empty value is parsed, if the parser does not reject empty values an item is added
to the resulting header. There can't be empty values. Added a test for it in AcceptEncoding.
This is the last bunch of headers that should use the new macro. Moved them out of
their own folder so that the macro works. Changed them, so that they are more in
line with the other headers.
BREAKING CHANGE: `AccessControlAllowHeaders` and `AccessControlRequestHeaders` values
are case insensitive now. `AccessControlAllowOrigin` variants are now `Any` and
`Value` to match the other headers.
`If-Match`, `If-None-Match` and `Vary` headers are either a "*" value meaning that the header
matches every possible item or a list of items, one of them must be matched to fulfil the condition.
BREAKING CHANGE: `If-Match`, `If-None-Match` and `Vary` item variant name changed to `Items`
Change `Etag` (only the `E` is capitalized) to `ETag` as it is written
in the relevant RFC.
BREAKING CHANGE: `Etag` header field is now `ETag` header field
The new macro handles single value headers, list headers, and list
headers with at least one item.
It creates the item for the header and contains its documentation. The
new macro allows handling
more header cases in the future, it will also be possible to include
tests inside the macro.
BREAKING CHANGE: Removed impl_header!() and impl_list_header!() macros,
use new header!() macro.
Using `time::Tm` directly in HTTP header fields requires special handling to parse and format
the header values., this stops us from using the header macros. By wrapping `time::Time` in a
`HttpDate`, we can use the `FromStr` and `Display` traits of `HttpDate` like for most other values.
BREAKING_CHANGE: All code using one of the `Date`, `Expires`, `If-Modified-Since`,
`If-Unmodified-Since`, `Last-Modified` header fields needs to wrap `time::Tm`
with `HttpDate`. Removed `FromStr` trait of `Date`, `If-Modified-Sice` and `If-Unmodified-Sice`,
implementing the trait here is inconsistent with other headers.
Adds strong and weak comparison to EntityTag as described in the RFC,
add tests for this. Make EntityTag safe to use by hiding the tag field,
this prevents users from inserting malicious values for the tag. Invalid
values can screw up header formatting and may allow to insert headers.
Introduce EntityTag::new(), .tag() and .set_tag() methods. Fix Display
trait for EntityTag. DQUOTES were missing. Remove custom formatting in ETag
header. Improve docs.
BREAKING_CHANGE: EntityTag.tag is private, use EntityTag.tag() and
EntityTag.set_tag("foobar") to access it.
