Struct State 

pub struct State<F: Family, Op, D: Digest> {
    pub leaf_count: Location<F>,
    pub pinned_nodes: Vec<D>,
    pub last_commit_op: Op,
    pub last_commit_proof: Proof<F, D>,
}

Authenticated state for initializing a compact-storage database at a target root.

Fields

leaf_count: Location<F>

Total number of operations/leaves in the target database.

pinned_nodes: Vec<D>

Pinned Merkle nodes for the current frontier.

last_commit_op: Op

The final commit operation at leaf_count - 1.

last_commit_proof: Proof<F, D>

Proof authenticating last_commit_op against the target root.

Trait Implementations

impl<F: Clone + Family, Op: Clone, D: Clone + Digest> Clone for State<F, Op, D>

fn clone(&self) -> State<F, Op, D>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Debug + Family, Op: Debug, D: Debug + Digest> Debug for State<F, Op, D>

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

Formats the value using the given formatter.

impl<F: Family, Op, D: Digest> EncodeSize for State<F, Op, D>

where Op: EncodeSize,

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<F: Family, Op, D: Digest> From<State<F, Op, D>> for FetchResult<F, Op, D>

fn from(state: State<F, Op, D>) -> Self

Converts to this type from the input type.

impl<F: Family, Op, D: Digest> Read for State<F, Op, D>

where Op: Read,

type Cfg = (RangeCfg<usize>, <Op as Read>::Cfg, usize)

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, CodecError>

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

impl<F: Family, Op, D: Digest> Write for State<F, Op, D>

where Op: Write,

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.
