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)`.
This removes the need for someone to use the `time` crate to create a
date compatible with HTTP headers. It now works with the `SystemTime`
type from the standard library.
BREAKING CHANGE: `HttpDate` no longer has public fields. Convert between
`HttpDate` and `SystemTime` as needed.
The `TE` header is used by a client to specify which
transfer encodings other than `chunked` it will accept.
It also specifies whether HTTP trailers are acceptable.
This commit also adds a `Trailers` variant to the
`hyper::header::shared::Encoding` enum.
Closes#1109
BREAKING CHANGE: The `Encoding` enum has an additional
variant, `Trailers`.
1. index out of bounds if semicolon is the last character
2. not a char boundary on non-ASCII input (only allow ASCII now)
Bugs found using `cargo fuzz`
BREAKING CHANGE: The `Preference` header had a typo in a variant and it's string representation,
change `Preference::HandlingLeniant` to `Preference::HandlingLenient`.
This removes the cookie crate, since it has an optional dependency on
openssl, which can cause massive breakage if toggled on. Instead, the
`Cookie` and `SetCookie` headers now just use a `String`. Anyone can
create any typed header, so it is easy to plug in different
implementations.
BREAKING CHANGE: The `Cookie` and `SetCookie` headers no longer use the
cookie crate. New headers can be written for any header, or the ones
provided in hyper can be accessed as strings.
Make hyper dependant on rust-language-tags providing complete parsing
and formatting of language tags. Remove builtin solution for simple
tags.
BREAKING CHANGE: AcceptLanguage and ContentLanguage use LanguageTag now,
Language removed from Hyper.
This allows more precise errors in the future and makes it easier to use
the try!() macro in some cases.
BREAKING CHANGE: Error enum extended. Return type of header/shared/
types changed.
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.
Using floating point numbers is problematic because comparison is inexact.
They also take more space than integral numbers in this case.
Add `FromPrimitve`, `ToPrimitive` and `Default` traits to quality newtype.
Closes: #330
BREAKING_CHANGE: Replace f32 quality values in quality items with a
Quality(u16) newtype. Valid values are from 0 to 1000.
Allow use of EntityTag in other headers that use entity tags.
BREAKING CHANGE: for any consumers of the Etag header, since the entity
tag is now in a tuple.
Currently headers are exported at many places. For example you can access
`Transfer-Encoding` header at `header`, `header::common` and
`header::common::transfer_encoding`. Per discussion on IRC with
@seanmonstar and @reem, all contents of headers will be exposed at `header`
directly. Parsing utilities will be exposed at `header::parsing`. Header
macros can now be used from other crates.
This breaks much code using headers. It should use everything it needs
directly from `header::`, encodings are exposed at `header::Encoding::`,
connection options are exposed at `header::ConnectionOption`.
- Some stray deriving -> derive changes
- use::{mod} -> use::{self}
- fmt.write -> fmt.write_str
This does not catch the last case of fmt.write_str in the
Show impl of a Header Item. This will need to be changed
separately.
