Struct CBORDecoder

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

Implementations

impl<'a> CBORDecoder<'a>

pub fn new(bytes: &'a [u8]) -> Self

pub fn read_slice(&mut self, n: usize) -> Result<&'a [u8], CBORError>

Consume and return n bytes starting at the current position.

pub fn position(&self) -> usize

pub fn finished(&self) -> bool

pub fn ensure_finished(&self) -> Result<(), CBORError>

pub fn remaining_buffer(&self) -> Result<&[u8], CBORError>

pub fn current(&self) -> Result<u8, CBORError>

Get the byte at the current position.

pub fn u8(&mut self) -> Result<u8, CBORError>

Decode a u8 value.

pub fn i8(&mut self) -> Result<i8, CBORError>

Decode an i8 value.

pub fn int_raw(&mut self) -> Result<u8, CBORError>

Get the raw i8 or u8 value.

pub fn str(&mut self) -> Result<&'a [u8], CBORError>

Decode a string slice.

pub fn bytes(&mut self) -> Result<&'a [u8], CBORError>

Decode a byte slice.

pub fn bytes_sized( &mut self, expected_size: usize, ) -> Result<&'a [u8], CBORError>

Decode a byte slice of an expected size.

pub fn array(&mut self) -> Result<usize, CBORError>

Begin decoding an array.

pub fn map(&mut self) -> Result<usize, CBORError>

Begin decoding a map.

pub fn as_usize(&mut self, b: u8) -> Result<usize, CBORError>

Decode a u8 value into usize.

pub fn type_of(b: u8) -> u8

Get the major type info of the given byte (highest 3 bits).

pub fn info_of(b: u8) -> u8

Get the additionl type info of the given byte (lowest 5 bits).

pub fn is_u8(byte: u8) -> bool

Check for: an unsigned integer encoded as a single byte

pub fn is_i8(byte: u8) -> bool

Check for: a negative integer encoded as a single byte

pub fn any_as_encoded(&mut self) -> Result<&'a [u8], CBORError>

Decode any (supported) CBOR item, but ignore its internal structure and just return the encoded data.

To have bound memory requirements, this depends on the encoded data to be in deterministic encoding, thus not having any indeterminate length items.

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

Formats the value using the given formatter.
