Module types

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

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

IterNameTypes

Trait shared by ASN1 SET, SEQUENCE, AND CHOICE that allows iterating over their field types.
