Module rasn::types

ASN.1 Data Types

The types modules is a collection of Rust types and data structures that are defined to represent various ASN.1 data types, and renamed to use ASN.1’s terminology.

Structs

• Any
  Represents a complete encoded ASN.1 value of any type. Usually identified with an ObjectIdentifier.
• BmpString
  A Basic Multilingual Plane (BMP) string, which is a subtype of UniversalString containing only the BMP set of characters.
• ConstrainedInteger
  A integer which has encoded constraint range between START and END.
• Explicit
  A newtype wrapper that will explicitly tag its value with T’s tag.
• FixedOctetString
• GeneralString
  A “general” string containing the C0 Controls plane, SPACE, Basic Latin, DELETE, and Latin-1 Supplement characters.
• Ia5String
  An string which only contains ASCII characters.
• Implicit
  A newtype wrapper that will implicitly tag its value with T’s tag.
• InstanceOf
  An instance of a defined object class.
• Integer
  A big signed integer type.
• NumericString
  A string which can only contain numbers or SPACE characters.
• ObjectIdentifier
  A global unique identifier that identifies an concept, such as a organisation, or encoding rules. The “owned” version of Oid.
• OctetString
  A cheaply cloneable and sliceable chunk of contiguous memory.
• Oid
  A reference to a global unique identifier that identifies an concept, such as a organisation, or encoding rules.
• PrintableString
  A string, which contains the characters defined in X.680 41.4 Section, Table 10.
• Tag
  An abstract representation of an ASN.1 tag that uniquely identifies a type within a ASN.1 module for codecs.
• TeletexString
  A string, which contains the characters defined in T.61 standard.
• Utf8String
  A UTF-8–encoded, growable string.
• VisibleString
  A string which contains a subset of the ISO 646 character set. Type should be constructed by using try_from or from methods.

Enums

• Class
  The class of tag identifying its category.
• Open
  An “open” type representing any valid ASN.1 type.
• TagTree
  The root or node in tree representing all of potential tags in a ASN.1 type. For most types this is only ever one level deep, except for CHOICE enums which will contain a set of nodes, that either point to a Leaf or another level of Choice.

Traits

• AsnType
  A trait representing any type that can represented in ASN.1.
• Choice
  A CHOICE value.
• Constructed
  A SET or SEQUENCE value.
• DecodeChoice
  A CHOICE value.
• Enumerated
  A ENUMERATED value.

Type Aliases

• BitStr
  A reference to a BIT STRING type.
• BitString
  The BIT STRING type.
• FixedBitString
  A fixed length BIT STRING type.
• GeneralizedTime
  The GeneralizedTime type.
• SequenceOf
  The SEQUENCE OF type.
• SetOf
  The SET OF type.
• UniversalString
  The UniversalString type.
• UtcTime
  The UTCTime type.

Derive Macros

• AsnType
  An automatic derive of the AsnType trait.
