Struct AwsChunkedDecoder 

pub struct AwsChunkedDecoder { /* private fields */ }

Incremental decoder for the aws-chunked content-encoding that modern AWS S3 clients (aws-cli, boto3 >= 1.36, aws-crt) apply by default to PutObject / UploadPart bodies when they send x-amz-content-sha256: STREAMING-AWS4-HMAC-SHA256-PAYLOAD (or STREAMING-UNSIGNED-PAYLOAD-TRAILER).

The wire format wraps the real payload in application-layer frames: <hex-size>[;chunk-signature=<hex>]\r\n<data>\r\n repeated, terminated by a 0-size chunk, then optional x-amz-trailer lines, then a final \r\n. hyper only strips HTTP Transfer-Encoding: chunked, NOT this Content-Encoding: aws-chunked framing — so without decoding, the size / signature lines and trailers get stored as the object’s bytes (silent corruption + a wrong ETag). This is fed incrementally because network frames do not align to chunk boundaries. Trailer lines (x-amz-checksum-<algo>:<v>) are collected so the service can verify the trailing checksum against the decoded bytes; see AwsChunkedDecoder::trailers.

Implementations

impl AwsChunkedDecoder

pub fn feed(&mut self, input: &[u8]) -> Result<Vec<u8>, MalformedChunk>

Feed a network frame; returns the decoded payload bytes it yielded. Errors only on a malformed chunk-size line.

pub fn trailers(&self) -> &[(String, String)]

The trailer headers read after the terminating zero-size chunk.

pub fn into_trailers(self) -> Vec<(String, String)>

Consume the decoder, returning its trailer headers.

Trait Implementations

impl Default for AwsChunkedDecoder

fn default() -> Self

Returns the “default value” for a type.
