Struct Shard 

pub struct Shard<C: Scheme, H: Hasher> { /* private fields */ }

A broadcastable shard of erasure coded data, including the coding commitment and the configuration used to code the data.

Implementations

impl<C: Scheme, H: Hasher> Shard<C, H>

pub const fn new(commitment: Commitment, index: u16, inner: C::Shard) -> Self

pub const fn index(&self) -> u16

Returns the index of this shard within the commitment.

pub const fn commitment(&self) -> Commitment

Returns the Commitment for this shard.

pub fn into_inner(self) -> C::Shard

Takes the inner shard.

Trait Implementations

impl<C: Scheme, H: Hasher> Clone for Shard<C, H>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Scheme, H: Hasher> Committable for Shard<C, H>

type Commitment = Commitment

The type of commitment produced by this object.

fn commitment(&self) -> Self::Commitment

Returns the unique commitment of the object as a Digest.

impl<C: Scheme, H: Hasher> EncodeSize for Shard<C, H>

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the working buffer for inline writes. Override alongside Write::write_bufs for types where large Bytes fields go via push; failing to do so will over-allocate.

impl<C: Scheme, H: Hasher> PartialEq for Shard<C, H>

fn eq(&self, other: &Self) -> 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.

impl<C: Scheme, H: Hasher> Read for Shard<C, H>

type Cfg = CodecConfig

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, cfg: &Self::Cfg) -> Result<Self, Error>

Reads a value from the buffer using the provided configuration cfg.

impl<C: Scheme, H: Hasher> Write for Shard<C, H>

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

fn write_bufs(&self, buf: &mut impl BufsMut)

Writes to a BufsMut, allowing existing Bytes chunks to be appended via BufsMut::push instead of written inline. Must encode to the same format as Write::write. Defaults to Write::write.
