Struct hyper::header::Headers
[−]
[src]
pub struct Headers { /* fields omitted */ }A map of header fields on requests and responses.
Methods
impl Headers[src]
pub fn new() -> Headers[src]
Creates a new, empty headers map.
pub fn set<H: Header + HeaderFormat>(&mut self, value: H)[src]
Set a header field to the corresponding value.
The field is determined by the type of the value being set.
pub fn get_raw(&self, name: &str) -> Option<&[Vec<u8>]>[src]
Access the raw value of a header.
Prefer to use the typed getters instead.
Example:
let raw_content_type = headers.get_raw("content-type");
pub fn set_raw<K: Into<Cow<'static, str>>>(
&mut self,
name: K,
value: Vec<Vec<u8>>
)[src]
&mut self,
name: K,
value: Vec<Vec<u8>>
)
Set the raw value of a header, bypassing any typed headers.
Note: This will completely replace any current value for this header name.
Example:
headers.set_raw("content-length", vec![b"5".to_vec()]);
pub fn append_raw<K: Into<Cow<'static, str>>>(
&mut self,
name: K,
value: Vec<u8>
)[src]
&mut self,
name: K,
value: Vec<u8>
)
Append a value to raw value of this header.
If a header already contains a value, this will add another line to it.
If a header doesnot exist for this name, a new one will be created with the value.
Example:
headers.append_raw("x-foo", b"bar".to_vec()); headers.append_raw("x-foo", b"quux".to_vec());
pub fn remove_raw(&mut self, name: &str)[src]
Remove a header set by set_raw
pub fn get<H: Header + HeaderFormat>(&self) -> Option<&H>[src]
Get a reference to the header field's value, if it exists.
pub fn get_mut<H: Header + HeaderFormat>(&mut self) -> Option<&mut H>[src]
Get a mutable reference to the header field's value, if it exists.
pub fn has<H: Header + HeaderFormat>(&self) -> bool[src]
Returns a boolean of whether a certain header is in the map.
Example:
let has_type = headers.has::<ContentType>();
pub fn remove<H: Header + HeaderFormat>(&mut self) -> bool[src]
Removes a header from the map, if one existed. Returns true if a header has been removed.
ⓘImportant traits for HeadersItems<'a>pub fn iter(&self) -> HeadersItems[src]
Returns an iterator over the header fields.
pub fn len(&self) -> usize[src]
Returns the number of headers in the map.
pub fn clear(&mut self)[src]
Remove all headers from the map.
