Expand description

types contains representations for ASN.1’s basic types, such as BOOLEANs or SEQUENCEs.

Structs§

  • BitString
    Representation of an ASN1 BIT STRING data element with corresponding constraints and distinguished values defining the individual bits. As defined in Rec. ITU-T X.680 (02/2021) §22
  • Boolean
    Representation of an ASN1 BOOLEAN data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §18
  • CharacterString
    Representation of an ASN1 Character String type data element with corresponding constraints. ASN1 Character String types include IA5String, UTF8String, VideotexString. As defined in Rec. ITU-T X.680 (02/2021) §39-§44
  • Choice
    Representation of an ASN1 CHOICE data element with corresponding members and extension information. As defined in Rec. ITU-T X.680 (02/2021) §29
  • ChoiceOption
    Representation of an single ASN1 CHOICE option.
  • ChoiceSelectionType
    Representation of a ASN1 selection type as used with ASN1 CHOICEs As defined in Rec. ITU-T X.680 (02/2021) §30
  • DistinguishedValue
    Representation of a ASN1 distinguished value, as seen in some INTEGER and BIT STRING declarations As defined in Rec. ITU-T X.680 (02/2021) §19.5 and §22.4
  • Enumeral
    Representation of a single member/enumeral of an ASN1 ENUMERATED data element.
  • Enumerated
    Representation of an ASN1 ENUMERATED data element with corresponding enumerals and extension information. As defined in Rec. ITU-T X.680 (02/2021) §20
  • GeneralizedTime
    Representation of an ASN1 GeneralizedTime data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §46
  • Integer
    Representation of an ASN1 INTEGER data element with corresponding constraints and distinguished values. As defined in Rec. ITU-T X.680 (02/2021) §19
  • ObjectIdentifier
    Representation of an ASN1 OBJECT IDENTIFIER data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §32
  • OctetString
    Representation of an ASN1 OCTET STRING data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §23
  • Real
    Representation of an ASN1 REAL data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §21
  • SequenceOrSet
    Representation of an ASN1 SEQUENCE or SET data element with corresponding members and extension information. Whether the struct describes a SEQUENCE or a SET is identified by the ASN1Type enum variant that holds this struct as a value (i.e. ASN1Type::Set(SequenceOrSet { .. }) or ASN1Type::Sequence(SequenceOrSet { .. })). As defined in Rec. ITU-T X.680 (02/2021) §25 and §27
  • SequenceOrSetMember
    Representation of an single ASN1 SEQUENCE or SET member.
  • SequenceOrSetOf
    Representation of an ASN1 SEQUENCE OF and SET OF data element with corresponding constraints and element type info Whether the struct describes a SEQUENCE OF or a SET OF is identified by the ASN1Type enum variant that holds this struct as a value (i.e. ASN1Type::SetOf(SequenceOrSetOf { .. }) or ASN1Type::SequenceOf(SequenceOrSetOf { .. })). As defined in Rec. ITU-T X.680 (02/2021) §26 and §28
  • Time
    Representation of an ASN1 TIME data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §38
  • UTCTime
    Representation of an ASN1 Universal time (a.k.a UTCTime) data element with corresponding constraints. As defined in Rec. ITU-T X.680 (02/2021) §47

Enums§

  • SequenceComponent
    Intermediate parsing type to parse COMPONENTS OF notation. SequenceComponent is an intermediary type that implementors of a [Backend] will usually not interact with. When parsing the body of an ASN.1 SEQUENCE or SET, the lexer distinguishes between a group of members (SequenceComponent::ComponentsOf) that is imnported from another ASN.1 data element using the COMPONENTS OF notation (i.e. Extending-Sequence ::= SEQUENCE { COMPONENTS OF Another-Sequence, added-field BOOLEAN }) and the regular member declaration (SequenceComponent::Member) (i.e. Simple-Sequence ::= SEQUENCE { field BOOLEAN }). When the lexer assembles the complete SequenceOrSet struct, it groups the parsed SequenceComponent items into the members and components_of fields of the SequenceOrSet struct. The linker will subsequently try to resolve the components_of identifiers.

Traits§

  • Constrainable
    Trait shared by all ASN1 types that can be constrained a.k.a subtyped. See also Rec. ITU-T X.680 (02/2021) §49 - §51
