TlsSetError

xmtp_mls_common::tls_set

Enum TlsSetError 

Source 
pub enum TlsSetError {
    DuplicateHash,
    Map(TlsMapError),
    Codec(Error),
}
Expand description

Error type for TlsSet operations.

Variants§

§

DuplicateHash

Two or more keys in the set produce the same SHA-256 digest.

Returned by TlsSet::apply_delta when building the hash index for RemoveByHash lookups. SHA-256 collisions are cryptographically infeasible to find by chance, so in practice this signals either:

  • A bug in Serialize for K producing identical bytes for distinct logically-different keys (e.g., a non-deterministic encoding), or
  • A deliberate adversarial attempt to seed the set with crafted entries.

We surface it as a defense-in-depth guarantee: RemoveByHash resolves to exactly one key, never silently picking one of several candidates.

§

Map(TlsMapError)

An underlying TlsMap error.

§

Codec(Error)

A TLS codec serialization error (from hashing a key).
