Struct HashMismatch 

pub struct HashMismatch;

The upstream delivered bytes that failed bao verification against the requested content root — a paid-but-corrupt delivery (the content-addressing invariant, ADR 014/038). Under ADR 038 the verifier is the per-chunk-group bao-tree decoder fed as bytes arrive, not a whole-blob re-hash, so this fires the moment any group’s proof mismatches. Returned (via anyhow) by this crate’s decoding consumers — [ClientRangedStore::ingest_stream] and the test-util in-memory decoder — so callers can downcast_ref to classify corruption (e.g. a reputation Corruption outcome) without matching on the error message string. The Display text is kept stable for logs and the existing requester tests. The node’s cache admit reports the same fault as CacheError::VerifyFailed / CacheError::HashMismatch, which decdn-node’s is_bao_corruption folds together with this type.

Trait Implementations

impl Debug for HashMismatch

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

Formats the value using the given formatter.

impl Display for HashMismatch

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

Formats the value using the given formatter.

impl Error for HashMismatch

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
