[−][src]Struct http_types::trailers::Trailers
A collection of trailing HTTP headers.
Implementations
impl Trailers
[src]
pub fn new() -> Self
[src]
Create a new instance of Trailers
.
pub fn insert(
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<Option<Vec<HeaderValue>>>
[src]
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<Option<Vec<HeaderValue>>>
Insert a header into the headers.
Examples
use http_types::Trailers; let mut trailers = Trailers::new(); trailers.insert("Content-Type", "text/plain")?;
pub fn append(
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<()>
[src]
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<()>
Append a header to the headers.
Unlike insert
this function will not override the contents of a header, but insert a
header if there aren't any. Or else append to the existing list of headers.
Examples
use http_types::Trailers; let mut trailers = Trailers::new(); trailers.append("Content-Type", "text/plain")?;
pub fn get(&self, name: &HeaderName) -> Option<&Vec<HeaderValue>>
[src]
Get a reference to a header.
pub fn get_mut(&mut self, name: &HeaderName) -> Option<&mut Vec<HeaderValue>>
[src]
Get a mutable reference to a header.
pub fn remove(&mut self, name: &HeaderName) -> Option<Vec<HeaderValue>>
[src]
Remove a header.
pub fn iter(&self) -> Iter
[src]
An iterator visiting all header pairs in arbitrary order.
pub fn iter_mut(&mut self) -> IterMut
[src]
An iterator visiting all header pairs in arbitrary order, with mutable references to the values.
pub fn names(&self) -> Names
[src]
An iterator visiting all header names in arbitrary order.
pub fn values(&self) -> Values
[src]
An iterator visiting all header values in arbitrary order.
Methods from Deref<Target = Headers>
pub fn insert(
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<Option<Vec<HeaderValue>>>
[src]
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<Option<Vec<HeaderValue>>>
Insert a header into the headers.
Not that this will replace all header values for a given header name.
If you wish to add header values for a header name that already exists
use Headers::append
pub fn append(
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<()>
[src]
&mut self,
name: impl TryInto<HeaderName>,
values: impl ToHeaderValues
) -> Result<()>
Append a header to the headers.
Unlike insert
this function will not override the contents of a header, but insert a
header if there aren't any. Or else append to the existing list of headers.
pub fn get(&self, name: &HeaderName) -> Option<&Vec<HeaderValue>>
[src]
Get a reference to a header.
pub fn get_mut(&mut self, name: &HeaderName) -> Option<&mut Vec<HeaderValue>>
[src]
Get a mutable reference to a header.
pub fn remove(&mut self, name: &HeaderName) -> Option<Vec<HeaderValue>>
[src]
Remove a header.
pub fn iter(&self) -> Iter
[src]
An iterator visiting all header pairs in arbitrary order.
pub fn iter_mut(&mut self) -> IterMut
[src]
An iterator visiting all header pairs in arbitrary order, with mutable references to the values.
pub fn names(&self) -> Names
[src]
An iterator visiting all header names in arbitrary order.
pub fn values(&self) -> Values
[src]
An iterator visiting all header values in arbitrary order.
