Struct ComputedDigests 

pub struct ComputedDigests {
    pub content_md5: Option<[u8; 16]>,
    pub crc32_be: Option<[u8; 4]>,
    pub crc32c_be: Option<[u8; 4]>,
    pub sha1: Option<[u8; 20]>,
    pub sha256: Option<[u8; 32]>,
    pub crc64nvme_be: Option<[u8; 8]>,
}

Finalised digest values for every algorithm whose hasher was active. Populated by the tee on the EOF poll and exposed via the DigestHandle returned by tee_into_hashers_with_handle; the PUT handler reads it after body consumption to compare against request trailer values (the chunked / SigV4-streaming SDK case where the checksum is delivered post-body rather than as a header).

Fields

content_md5: Option<[u8; 16]>

crc32_be: Option<[u8; 4]>

crc32c_be: Option<[u8; 4]>

sha1: Option<[u8; 20]>

sha256: Option<[u8; 32]>

crc64nvme_be: Option<[u8; 8]>

Implementations

impl ComputedDigests

pub fn compare_b64(&self, algorithm: &str, claim_b64: &str) -> S3Result<()>

Compare one finalised digest against a base64-encoded trailer-supplied claim. Returns Err(BadDigest) on mismatch, Err(InvalidDigest) on malformed input, Ok(()) on match. algorithm is the wire header name used in the error message; the match is case-insensitive because HTTP header field names are case-insensitive per RFC 9110 §5.1 and AWS SDKs may announce trailers as X-Amz-Checksum-Crc32c (or any other casing) — we keep the original casing in error messages for fidelity but normalise for the dispatch.

Trait Implementations

impl Clone for ComputedDigests

fn clone(&self) -> ComputedDigests

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ComputedDigests

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

Formats the value using the given formatter.

impl Default for ComputedDigests

fn default() -> ComputedDigests

Returns the “default value” for a type.
