Trait Implementations

impl AsnType for BitString

const TAG: Tag = Tag::BIT_STRING

The associated tag for the type.

const IDENTIFIER: Identifier = Identifier::BIT_STRING

Identifier of an ASN.1 type as specified in the original specification if not identical with the identifier of Self

const TAG_TREE: TagTree = _

The root of this type’s tree of tag’s if it a CHOICE type, otherwise its Leaf that points Self::TAG.

const CONSTRAINTS: Constraints = Constraints::NONE

The set of constraints for values of the given type.

const IS_CHOICE: bool = false

Whether the type is choice type. PER/OER encoding rules require this knowledge.

fn is_present(&self) -> bool

Whether the type is present with value. OPTIONAL fields are common in SEQUENCE or SET.

impl Decode for BitString

fn decode_with_tag_and_constraints<D: Decoder>( decoder: &mut D, tag: Tag, constraints: Constraints, ) -> Result<Self, D::Error>

Decode this value implicitly tagged with tag from a given ASN.1 decoder with a set of constraints on what values of that type are allowed.

fn decode<D: Decoder>(decoder: &mut D) -> Result<Self, D::Error>

Decode this value from a given ASN.1 decoder.

fn decode_with_tag<D: Decoder>( decoder: &mut D, tag: Tag, ) -> Result<Self, D::Error>

Decode this value implicitly tagged with tag from a given ASN.1 decoder.

fn decode_with_constraints<D: Decoder>( decoder: &mut D, constraints: Constraints, ) -> Result<Self, D::Error>

Decode this value from a given ASN.1 decoder with a set of constraints on what values of that type are allowed.

impl Encode for BitString

fn encode_with_tag_and_constraints<'b, E: Encoder<'b>>( &self, encoder: &mut E, tag: Tag, constraints: Constraints, identifier: Identifier, ) -> Result<(), E::Error>

Encode this value with tag into the given crate::Encoder with the constraints the values this is allowed to encode into.

fn encode<'b, E: Encoder<'b>>(&self, encoder: &mut E) -> Result<(), E::Error>

Encodes self’s data into the given crate::Encoder.

fn encode_with_tag<'b, E: Encoder<'b>>( &self, encoder: &mut E, tag: Tag, ) -> Result<(), E::Error>

Encode this value with tag into the given crate::Encoder.

fn encode_with_identifier<'b, E: Encoder<'b>>( &self, encoder: &mut E, identifier: Identifier, ) -> Result<(), E::Error>

Encode this value with identifier into the given crate::Encoder.

fn encode_with_tag_and_identifier<'b, E: Encoder<'b>>( &self, encoder: &mut E, tag: Tag, identifier: Identifier, ) -> Result<(), E::Error>

Encode this value with tag and identifier into the given crate::Encoder.

fn encode_with_constraints<'b, E: Encoder<'b>>( &self, encoder: &mut E, constraints: Constraints, ) -> Result<(), E::Error>

Encode this value into the given crate::Encoder with the constraints the values this is allowed to encode into.

fn encode_with_constraints_and_identifier<'b, E: Encoder<'b>>( &self, encoder: &mut E, constraints: Constraints, identifier: Identifier, ) -> Result<(), E::Error>

Encode this value into the given crate::Encoder with identifier and the constraints the values this is allowed to encode into.
