Struct ProofBuf

pub struct ProofBuf { /* private fields */ }

A buffer containing a proof for a block of data.

Implementations

impl ProofBuf

pub fn new(tree: &[[u8; 32]], block: usize) -> Self

Construct a new proof for the given block index from the provided tree.

pub fn resume(tree: &[[u8; 32]], block: usize) -> Self

Construct proof for the given block number assuming that previous blocks have already been sent.

pub fn as_slice(&self) -> &[u8]

Returns the proof as a slice.

pub fn len(&self) -> usize

Returns the length of the proof.

pub fn is_empty(&self) -> bool

Returns if the buffer is empty.

Trait Implementations

impl AsRef<[u8]> for ProofBuf

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<[u8]> for ProofBuf

fn borrow(&self) -> &[u8]

Immutably borrows from an owned value.

impl Debug for ProofBuf

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

Formats the value using the given formatter.

impl PartialEq<&[u8]> for ProofBuf

fn eq(&self, other: &&[u8]) -> 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.
