Struct Target 

pub struct Target<F: Family, D: Digest> {
    pub root: D,
    pub leaf_count: Location<F>,
}

Compact-sync target for a compact-storage database.

Compact sync authenticates only the final committed root and total leaf count. Unlike replay sync, there is no lower replay bound here because compact sync does not transfer or reconstruct historical operations.

Fields

root: D

Authenticated root of the committed compact state.

leaf_count: Location<F>

Total committed operations/leaves in that state.

Implementations

impl<F: Family, D: Digest> Target<F, D>

pub const fn new(root: D, leaf_count: Location<F>) -> Self

Create a compact-sync target.

pub fn validate(&self) -> Result<(), &'static str>

Validate a compact target that may have been constructed programmatically.

Trait Implementations

impl<F: Family, D: Digest> Clone for Target<F, D>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

impl<F: Family, D: Digest> EncodeSize for Target<F, D>

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, D: Digest> Eq for Target<F, D>

impl<F: Family, D: Digest> PartialEq for Target<F, D>

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

Equality operator ==.

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

Inequality operator !=.

impl<F: Family, D: Digest> Read for Target<F, D>

type Cfg = ()

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, _: &()) -> Result<Self, CodecError>

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

impl<F: Family, D: Digest> Write for Target<F, D>

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.
