True for keys that are only AURA and Grandpa

Trait Implementations

impl Clone for CandidateKeys

fn clone(&self) -> CandidateKeys

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CandidateKeys

impl Decode for CandidateKeys

Custom backward compatibile Decode. See comment on the Encode implementation.

fn decode<I: Input>(input: &mut I) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for CandidateKeys

Backward compatible [Encode] for CandidateKeys. After node update InherentData would be encoded with this version but runtime would still know PermissionedCandidateData and CandidateRegistration that have AuraPublicKey and GrandpaPublicKey fields instead of CandidateKeys field. To support existing chains, when keys are AURA and Grandpa, CandidateKeys is encoded exactly like in previous version. If other key set is used in the place where AURA vector lenght is encoded, Compact(u32::MAX) is encoded to enable discrimination between the types that has to be decoded. The represtation is either: Legacy: AuraKeySize, AuraKeyBytes, GrandpaKeySize, GrandpaKeyBytes Generic: u32::MAX, CandidateKeysVector AuraKeySize cannot be u32::MAX (won’t fit on Cardano), so when it is encountered, we know that the generic representation is used.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<T: Output + ?Sized>(&self, dest: &mut T)

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl From<Vec<([u8; 4], Vec<u8>)>> for CandidateKeys

fn from(value: Vec<([u8; 4], Vec<u8>)>) -> Self

Converts to this type from the input type.

impl Hash for CandidateKeys

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

impl Ord for CandidateKeys

fn cmp(&self, other: &CandidateKeys) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

impl PartialEq for CandidateKeys

fn eq(&self, other: &CandidateKeys) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
