Struct RecordValidator 

pub struct RecordValidator { /* private fields */ }

Validates exactly one canonical record supplied in arbitrary fragments.

feed returns how many bytes it consumed. Once the record is complete it consumes nothing more, so bytes that follow the record stay with the caller. Errors are terminal: later input cannot turn the validator into a record.

Implementations

impl RecordValidator

pub fn new() -> Self

pub fn feed(&mut self, input: &[u8]) -> Result<usize, RecordError>

Consume a prefix of input and return its length. Stops at the record’s end; the remaining input is not part of this record.

pub fn canonical_len(&self) -> Option<usize>

The exact canonical length once the complete prefix has been read. It is not evidence that the data, hashes or Mark are valid.

pub fn prefix(&self) -> &[u8]

The canonical bytes before the Blob data received so far: the complete prefix once canonical_len is known.

pub fn is_complete(&self) -> bool

Whether the record has been completely received and verified.

pub fn finish(self) -> Result<ValidatedHeader, RecordError>

The verified header of a complete record.

Trait Implementations

impl Debug for RecordValidator

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

Formats the value using the given formatter.

impl Default for RecordValidator

fn default() -> Self

Returns the “default value” for a type.
