Enum Codec

#[non_exhaustive]
pub enum Codec {
    Aper,
    Ber,
    Cer,
    Der,
    Uper,
    Jer,
    Oer,
    Coer,
}

A set of supported ASN.1 codecs. Can be used to dynamically encode types into different codecs at runtime.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Aper

X.691 — Packed Encoding Rules (Aligned)

Ber

X.690 — Basic Encoding Rules

Cer

X.690 — Canonical Encoding Rules

Der

X.690 — Distinguished Encoding Rules

Uper

X.691 — Packed Encoding Rules (Unaligned)

Jer

JSON Encoding Rules

Oer

X.696 — Octet Encoding Rules

Coer

X.696 — Canonical Octet Encoding Rules

Implementations

impl Codec

pub fn encode_to_binary<T: Encode>( self, value: &T, ) -> Result<Vec<u8>, EncodeError>

Encodes a given value based on the value of Codec. This method shall be used when using binary-based encoding rules.

Errors

• If the value fails to be encoded returns EncodeError struct.

pub fn decode_from_binary<D: Decode>( &self, input: &[u8], ) -> Result<D, DecodeError>

Decodes input to D based on the value of Codec. This method shall be used when using binary-based encoding rules.

Errors

• If D cannot be decoded from input returns DecodeError struct.

pub fn encode_to_string<T: Encode>( self, value: &T, ) -> Result<String, EncodeError>

Encodes a given value based on the value of Codec. This method shall be used when using text-based encoding rules.

Errors

• If the value fails to be encoded, or if trying to encode using binary-based encoding rules, returns EncodeError struct.

pub fn decode_from_str<D: Decode>(&self, input: &str) -> Result<D, DecodeError>

Decodes input to D based on the value of Codec. This method shall be used when using text-based encoding rules.

Errors

• If D cannot be decoded from input, or if trying to decode using binary-based encoding rules, returns DecodeError struct.

Trait Implementations

impl Clone for Codec

fn clone(&self) -> Codec

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Codec

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

Formats the value using the given formatter.

impl Display for Codec

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

Formats the value using the given formatter.

impl Ord for Codec

fn cmp(&self, other: &Codec) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Codec

fn eq(&self, other: &Codec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Codec

fn partial_cmp(&self, other: &Codec) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
