Enum phron_finality::sync::data::BranchKnowledge

pub enum BranchKnowledge {
    LowestId(BlockId),
    TopImported(BlockId),
}

Additional information about the branch connecting the top finalized block with a given one. All the variants are exhaustive and exclusive due to the properties of the Forest structure.

Variants

LowestId(BlockId)

ID of the oldest known ancestor if none of them are imported. It must be different from the, imported by definition, root.

TopImported(BlockId)

ID of the top imported ancestor if any of them is imported. Since imported vertices are connected to the root, the oldest known ancestor is, implicitly, the root.

Trait Implementations

impl Clone for BranchKnowledge

fn clone(&self) -> BranchKnowledge

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BranchKnowledge

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

Formats the value using the given formatter.

impl Decode for BranchKnowledge

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

Attempt to deserialise the value from input.

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

where I: Input,

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 BranchKnowledge

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

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 PartialEq for BranchKnowledge

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

This method tests for self and other values to be equal, and is used by ==.

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

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