Struct Cbor 

pub struct Cbor<T>(pub T);

CBOR Extractor / Response.

When used as an extractor, it can deserialize request bodies into some type that implements serde::Deserialize. The request will be rejected (and a CborRejection will be returned) if:

• The request doesn’t have a Content-Type: application/cbor (or similar) header.
• The body doesn’t contain syntactically valid CBOR.
• The body contains syntactically valid CBOR but it couldn’t be deserialized into the target type.
• Buffering the request body fails.

⚠️ Since parsing CBOR requires consuming the request body, the Cbor extractor must be last if there are multiple extractors in a handler. See “the order of extractors”

Implementations

impl<T> Cbor<T>

where T: DeserializeOwned,

pub fn from_bytes(bytes: &[u8]) -> Result<Self, CborRejection>

Construct a Cbor<T> from a byte slice.

This method attempts to deserialize the provided bytes as CBOR data. Returns a CborRejection if deserialization fails.

Trait Implementations

impl<T> From<T> for Cbor<T>

fn from(inner: T) -> Self

Create a Cbor<T> from the inner value.

This is a convenience constructor that wraps any value in the Cbor struct.

impl<S, T> FromRequest<S> for Cbor<T>

where S: Send + Sync, T: DeserializeOwned,

async fn from_request(req: Request, state: &S) -> Result<Self, Self::Rejection>

Extract a CBOR payload from the request body.

This implementation validates the content type and deserializes the CBOR data. Returns a CborRejection if validation or deserialization fails.

type Rejection = CborRejection

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

impl<T> IntoResponse for Cbor<T>

where T: Serialize,

fn into_response(self) -> Response

Convert the CBOR payload into an HTTP response.

This serializes the inner value to CBOR format and sets the appropriate Content-Type: application/cbor header. Returns a 500 Internal Server Error if serialization fails.
