Struct der::Decoder

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

DER 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 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.

pub fn any(&mut self) -> Result<Any<'a>>

Attempt to decode an ASN.1 ANY value.

pub fn bit_string(&mut self) -> Result<BitString<'a>>

Attempt to decode an ASN.1 BIT STRING.

pub fn null(&mut self) -> Result<Null>

Attempt to decode an ASN.1 NULL value.

pub fn octet_string(&mut self) -> Result<OctetString<'a>>

Attempt to decode an ASN.1 OCTET STRING.

pub fn oid(&mut self) -> Result<ObjectIdentifier>

This is supported on crate feature oid only.

Attempt to decode an ASN.1 OBJECT IDENTIFIER.

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

Attempt to decode an ASN.1 OPTIONAL value.

pub fn sequence<F, T>(&mut self, f: F) -> Result<T> where
    F: FnOnce(&mut Decoder<'a>) -> Result<T>, 

Attempt to decode an ASN.1 SEQUENCE, creating a new nested Decoder and calling the provided argument with it.

Trait Implementations

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

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

Formats the value using the given formatter.

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

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

Performs the conversion.
