Implementations
impl AcceptEncoding
[src]
pub fn new() -> AcceptEncoding
[src]
Create a new instance of AcceptEncoding
.
pub fn from_headers(
headers: impl AsRef<Headers>
) -> Result<Option<AcceptEncoding>, Error>
[src]
headers: impl AsRef<Headers>
) -> Result<Option<AcceptEncoding>, Error>
Create an instance of AcceptEncoding
from a Headers
instance.
pub fn push(&mut self, prop: impl Into<EncodingProposal>)
[src]
Push a directive into the list of entries.
pub fn wildcard(&self) -> bool
[src]
Returns true
if a wildcard directive was passed.
pub fn set_wildcard(&mut self, wildcard: bool)
[src]
Set the wildcard directive.
pub fn sort(&mut self)
[src]
Sort the header directives by weight.
Headers with a higher q=
value will be returned first. If two
directives have the same weight, the directive that was declared later
will be returned first.
pub fn negotiate(
&mut self,
available: &[Encoding]
) -> Result<ContentEncoding, Error>
[src]
&mut self,
available: &[Encoding]
) -> Result<ContentEncoding, Error>
Determine the most suitable Content-Type
encoding.
Errors
If no suitable encoding is found, an error with the status of 406
will be returned.
pub fn apply(&self, headers: impl AsMut<Headers>)
[src]
Sets the Accept-Encoding
header.
pub fn name(&self) -> HeaderName
[src]
Get the HeaderName
.
pub fn value(&self) -> HeaderValue
[src]
Get the HeaderValue
.
pub fn iter(&self) -> Iter<'_>ⓘNotable traits for Iter<'a>
impl<'a> Iterator for Iter<'a> type Item = &'a EncodingProposal;
[src]
Notable traits for Iter<'a>
impl<'a> Iterator for Iter<'a> type Item = &'a EncodingProposal;
An iterator visiting all entries.
pub fn iter_mut(&mut self) -> IterMut<'_>ⓘNotable traits for IterMut<'a>
impl<'a> Iterator for IterMut<'a> type Item = &'a mut EncodingProposal;
[src]
Notable traits for IterMut<'a>
impl<'a> Iterator for IterMut<'a> type Item = &'a mut EncodingProposal;
An iterator visiting all entries.
