Struct ShardSlot 

pub struct ShardSlot<T> { /* private fields */ }

A reusable shard container for reconstruction workflows.

Unlike Option<Vec<_>>, this keeps ownership of the backing buffer even when the shard is marked missing, which lets callers reuse preallocated storage across repeated reconstruct calls.

Implementations

impl<T> ShardSlot<T>

pub fn new_present(data: T) -> Self

Create a shard slot whose data is already present.

pub fn new_missing(data: T) -> Self

Create a shard slot whose buffer exists but is currently marked missing.

pub fn with_present(data: T, present: bool) -> Self

Create a shard slot with an explicit presence flag.

pub fn is_present(&self) -> bool

Returns whether the shard is currently marked present.

pub fn mark_present(&mut self)

Mark the shard as present.

pub fn mark_missing(&mut self)

Mark the shard as missing while retaining ownership of its buffer.

pub fn as_inner(&self) -> &T

Access the inner storage regardless of presence state.

pub fn as_inner_mut(&mut self) -> &mut T

Mutably access the inner storage regardless of presence state.

pub fn into_inner(self) -> T

Consume the slot and return the inner storage.

Trait Implementations

fn clone(&self) -> ShardSlot<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for ShardSlot<T>

Inequality operator !=.

impl<F: Field, T: AsRef<[F::Elem]> + AsMut<[F::Elem]>> ReconstructShard<F> for ShardSlot<T>

fn len(&self) -> Option<usize>

The size of the shard data; None if empty.

fn get(&mut self) -> Option<&mut [F::Elem]>

Get a mutable reference to the shard data, returning None if uninitialized.

fn get_or_initialize(&mut self, len: usize) -> ReconstructInitResult<'_, F>
