[−][src]Struct sequoia_openpgp::cert::KeyringValidator
Used to help validate that a packet sequence is a valid key ring.
Implementations
impl KeyringValidator
[src]
pub fn new() -> Self
[src]
Instantiates a new KeyringValidator
.
pub fn is_keyring(&self) -> bool
[src]
Returns whether the packet sequence is a valid keyring.
Note: a KeyringValidator
will only return this after
KeyringValidator::finish
has been called.
pub fn is_keyring_prefix(&self) -> bool
[src]
Returns whether the packet sequence forms a valid keyring prefix.
Note: a KeyringValidator
will only return this before
KeyringValidator::finish
has been called.
pub fn is_err(&self) -> bool
[src]
Returns whether the packet sequence is definitely not a valid keyring.
pub fn push_token(&mut self, token: Token)
[src]
Add the token token
to the token stream.
pub fn push(&mut self, tag: Tag)
[src]
Add a packet of type tag
to the token stream.
pub fn finish(&mut self)
[src]
Notes that the entire message has been seen.
This function may only be called once.
Once called, this function will no longer return
KeyringValidity::KeyringPrefix
.
pub fn check(&self) -> KeyringValidity
[src]
Returns whether the token stream corresponds to a valid keyring.
This returns a tri-state: if the packet sequence is a valid
Keyring, it returns KeyringValidity::Keyring
, if the packet
sequence is invalid, then it returns KeyringValidity::Error
.
If the packet sequence that has been processed so far is a
valid prefix, then it returns
KeyringValidity::KeyringPrefix
.
Note: if KeyringValidator::finish()
hasn't been called,
then this function will only ever return either
KeyringValidity::KeyringPrefix
or KeyringValidity::Error
.
Once KeyringValidity::finish()
has been called, then it will
only return either KeyringValidity::Keyring
or
KeyringValidity::Error
.
