Struct KeyDeserializer 

pub struct KeyDeserializer<'a> { /* private fields */ }

Handles decoding of sequential serialized key payloads.

Implementations

impl<'a> KeyDeserializer<'a>

pub fn new(data: &'a [u8], base: Option<u64>) -> Result<(Self, usize), Error>

Parses a serialized chunked key from the front of data.

Returns the deserializer positioned at the key payload, along with the total bytes consumed in data (headers + payload chunks).

pub fn is_empty(&self) -> bool

Returns true if all payload bytes have been consumed.

pub fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Reads exactly buf.len() bytes into buf. Non-terminal fields are assumed to fit within the initial chunk.

pub fn read_u64(&mut self) -> Result<u64, Error>

Reads a 64-bit unsigned integer. If a base was provided and this is the first item, adds the base to reconstruct the original value.

pub fn read_varint(&mut self) -> Result<u64, Error>

Extracts an order-preserving decoded 64-bit variable length integer from stream.

pub fn read_last(&mut self) -> Result<Vec<u8>, Error>

Consumes and returns all remaining bytes in the key payload.
