Struct rocket_http::hyper::body::Body
source · pub struct Body { /* private fields */ }
Expand description
A stream of Bytes
, used when receiving bodies.
A good default HttpBody
to use in many
applications.
Note: To read the full body, use body::to_bytes
or body::aggregate
.
Implementations§
source§impl Body
impl Body
sourcepub fn empty() -> Body
pub fn empty() -> Body
Create an empty Body
stream.
Example
use hyper::{Body, Request};
// create a `GET /` request
let get = Request::new(Body::empty());
sourcepub fn channel() -> (Sender, Body)
pub fn channel() -> (Sender, Body)
Create a Body
stream with an associated sender half.
Useful when wanting to stream chunks from another thread.
sourcepub fn wrap_stream<S, O, E>(stream: S) -> Bodywhere
S: Stream<Item = Result<O, E>> + Send + 'static,
O: Into<Bytes> + 'static,
E: Into<Box<dyn Error + Sync + Send>> + 'static,
pub fn wrap_stream<S, O, E>(stream: S) -> Bodywhere S: Stream<Item = Result<O, E>> + Send + 'static, O: Into<Bytes> + 'static, E: Into<Box<dyn Error + Sync + Send>> + 'static,
Wrap a futures Stream
in a box inside Body
.
Example
let chunks: Vec<Result<_, std::io::Error>> = vec![
Ok("hello"),
Ok(" "),
Ok("world"),
];
let stream = futures_util::stream::iter(chunks);
let body = Body::wrap_stream(stream);
Optional
This function requires enabling the stream
feature in your
Cargo.toml
.

§fn fg(&self, value: Color) -> Painted<&T>
fn fg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the foreground set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like red()
and
green()
, which have the same functionality but are
pithier.
Example
Set foreground color to white using fg()
:
use yansi::{Paint, Color};
painted.fg(Color::White);
Set foreground color to white using white()
.
use yansi::Paint;
painted.white();

§fn bg(&self, value: Color) -> Painted<&T>
fn bg(&self, value: Color) -> Painted<&T>
Returns a styled value derived from self
with the background set to
value
.
This method should be used rarely. Instead, prefer to use color-specific
builder methods like on_red()
and
on_green()
, which have the same functionality but
are pithier.
Example
Set background color to red using fg()
:
use yansi::{Paint, Color};
painted.bg(Color::Red);
Set background color to red using on_red()
.
use yansi::Paint;
painted.on_red();

§fn attr(&self, value: Attribute) -> Painted<&T>
fn attr(&self, value: Attribute) -> Painted<&T>
Enables the styling [Attribute
] value
.
This method should be used rarely. Instead, prefer to use
attribute-specific builder methods like bold()
and
underline()
, which have the same functionality
but are pithier.
Example
Make text bold using attr()
:
use yansi::{Paint, Attribute};
painted.attr(Attribute::Bold);
Make text bold using using bold()
.
use yansi::Paint;
painted.bold();
§fn rapid_blink(&self) -> Painted<&T>
fn rapid_blink(&self) -> Painted<&T>
§fn quirk(&self, value: Quirk) -> Painted<&T>
fn quirk(&self, value: Quirk) -> Painted<&T>
Enables the yansi
[Quirk
] value
.
This method should be used rarely. Instead, prefer to use quirk-specific
builder methods like mask()
and
wrap()
, which have the same functionality but are
pithier.
Example
Enable wrapping using .quirk()
:
use yansi::{Paint, Quirk};
painted.quirk(Quirk::Wrap);
Enable wrapping using wrap()
.
use yansi::Paint;
painted.wrap();
§fn whenever(&self, value: Condition) -> Painted<&T>
fn whenever(&self, value: Condition) -> Painted<&T>
Conditionally enable styling based on whether the [Condition
] value
applies. Replaces any previous condition.
See the crate level docs for more details.
Example
Enable styling painted
only when both stdout
and stderr
are TTYs:
use yansi::{Paint, Condition};
painted.red().on_yellow().whenever(Condition::STDOUTERR_ARE_TTY);
