Struct flexiber::Decoder

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

BER-TLV decoder.

Implementations

impl<'a> Decoder<'a>

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

Create a new decoder for the given byte slice.

pub fn decode<T: Decodable<'a>>(&mut self) -> Result<T>

Decode a value which impls the Decodable trait.

pub fn decode_tagged_value<T: Decodable<'a> + TagLike, V: Decodable<'a>>(
    &mut self,
    tag: T
) -> Result<V>

Decode a TaggedValue with tag checked to be as expected, returning the value

pub fn decode_tagged_slice<T: Decodable<'a> + TagLike>(
    &mut self,
    tag: T
) -> Result<&'a [u8]>

Decode a TaggedSlice with tag checked to be as expected, returning the value

pub fn error<T>(&mut self, kind: ErrorKind) -> Result<T>

Return an error with the given ErrorKind, annotating it with context about where the error occurred.

pub fn is_failed(&self) -> bool

Did the decoding operation fail due to an error?

pub fn finish<T>(self, value: T) -> Result<T>

Finish decoding, returning the given value if there is no remaining data, or an error otherwise

pub fn is_finished(&self) -> bool

Have we decoded all of the bytes in this Decoder?

Returns false if we’re not finished decoding or if a fatal error has occurred.

Trait Implementations

impl<'a> Debug for Decoder<'a>

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

Formats the value using the given formatter.

impl<'a> From<&'a [u8]> for Decoder<'a>

fn from(bytes: &'a [u8]) -> Decoder<'a>

Converts to this type from the input type.
