Implementations§

source§

impl Tag

source

pub fn valid_start_of_message(&self) -> bool

Returns whether the Tag can be at the start of a valid message.

Certs can start with PublicKey, TSKs with a SecretKey.

Messages start with a OnePassSig, Signature (old style non-one pass signatures), PKESK, SKESK, CompressedData, or Literal.

Signatures can standalone either as a detached signature, a third-party certification, or a revocation certificate.

source

pub fn variants() -> impl Iterator<Item = Tag>

Returns an iterator over all valid variants.

Returns an iterator over all known variants. This does not include the Tag::Reserved, Tag::Private, or Tag::Unknown variants.
