Struct ChecksumBody

pub struct ChecksumBody<InnerBody> { /* private fields */ }

A body-wrapper that will calculate the InnerBody’s checksum and emit an error if it doesn’t match the precalculated checksum.

Implementations

impl ChecksumBody<SdkBody>

pub fn new( body: SdkBody, checksum: Box<dyn HttpChecksum>, precalculated_checksum: Bytes, ) -> Self

Given an SdkBody, a Box<dyn HttpChecksum>, and a precalculated checksum represented as Bytes, create a new ChecksumBody<SdkBody>.

Trait Implementations

impl Body for ChecksumBody<SdkBody>

type Data = Bytes

Values yielded by the Body.

type Error = Box<dyn Error + Send + Sync>

The error type this Body might generate.

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

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

fn poll_trailers( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<Option<HeaderMap<HeaderValue>>, Self::Error>>

Poll for an optional single HeaderMap of trailers.

fn is_end_stream(&self) -> bool

Returns true when the end of stream has been reached.

fn size_hint(&self) -> SizeHint

Returns the bounds on the remaining length of the stream.

fn data(&mut self) -> Data<'_, Self>

where Self: Sized + Unpin,

Returns future that resolves to next data chunk, if any.

fn trailers(&mut self) -> Trailers<'_, Self>

where Self: Sized + Unpin,

Returns future that resolves to trailers, if any.

fn map_data<F, B>(self, f: F) -> MapData<Self, F>

where Self: Sized, F: FnMut(Self::Data) -> B, B: Buf,

Maps this body’s data value to a different value.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F>

where Self: Sized, F: FnMut(Self::Error) -> E,

Maps this body’s error value to a different value.

fn boxed(self) -> BoxBody<Self::Data, Self::Error>

where Self: Sized + Send + Sync + 'static,

Turn this body into a boxed trait object.

fn boxed_unsync(self) -> UnsyncBoxBody<Self::Data, Self::Error>

where Self: Sized + Send + 'static,
