axum_core::body

Struct Body

pub struct Body(/* private fields */);

Expand description

The body type used in axum requests and responses.

Implementations§

impl Body

pub fn new<B>(body: B) -> Self
where B: Body<Data = Bytes> + Send + 'static, B::Error: Into<BoxError>,

Create a new Body that wraps another http_body::Body.

pub fn empty() -> Self

Create an empty body.

pub fn from_stream<S>(stream: S) -> Self
where S: TryStream + Send + 'static, S::Ok: Into<Bytes>, S::Error: Into<BoxError>,

Create a new Body from a Stream.

pub fn into_data_stream(self) -> BodyDataStream

Convert the body into a Stream of data frames.

Non-data frames (such as trailers) will be discarded. Use http_body_util::BodyStream if you need a Stream of all frame types.

Trait Implementations§

impl Body for Body

type Data = Bytes

Values yielded by the Body.

type Error = Error

The error type this Body might generate.

fn poll_frame( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Result<Frame<Self::Data>, Self::Error>>>

Attempt to pull out the next data buffer of this stream.

fn size_hint(&self) -> SizeHint

Returns the bounds on the remaining length of the stream. Read more

fn is_end_stream(&self) -> bool

Returns true when the end of stream has been reached. Read more

impl Debug for Body

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

impl Default for Body

fn default() -> Self

Returns the “default value” for a type. Read more

impl From<&'static [u8]> for Body

fn from(buf: &'static [u8]) -> Self

Converts to this type from the input type.

impl From<&'static str> for Body

fn from(buf: &'static str) -> Self

Converts to this type from the input type.

impl From<()> for Body

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<Bytes> for Body

fn from(buf: Bytes) -> Self

Converts to this type from the input type.

impl From<Cow<'static, [u8]>> for Body

fn from(buf: Cow<'static, [u8]>) -> Self

Converts to this type from the input type.

impl From<Cow<'static, str>> for Body

fn from(buf: Cow<'static, str>) -> Self

Converts to this type from the input type.

impl From<String> for Body

fn from(buf: String) -> Self

Converts to this type from the input type.

impl From<Vec<u8>> for Body

fn from(buf: Vec<u8>) -> Self

Converts to this type from the input type.

impl<S> FromRequest<S> for Body
where S: Send + Sync,

type Rejection = Infallible

If the extractor fails it’ll use this “rejection” type. A rejection is a kind of error that can be converted into a response.

fn from_request<'life0, 'async_trait>( req: Request, _: &'life0 S, ) -> Pin<Box<dyn Future<Output = Result<Self, Self::Rejection>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Perform the extraction.

impl IntoResponse for Body

fn into_response(self) -> Response

Create a response.

Auto Trait Implementations§

impl Freeze for Body

impl !RefUnwindSafe for Body

impl Send for Body

impl !Sync for Body

impl Unpin for Body

impl !UnwindSafe for Body

fn map_frame<F, B>(self, f: F) -> MapFrame<Self, F>

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
