Trait AsnType

pub trait AsnType {
    const TAG: Tag;
    const TAG_TREE: TagTree = _;
    const CONSTRAINTS: Constraints = Constraints::NONE;

}

Expand description

A trait representing any type that can represented in ASN.1.

Required Associated Constants§

const TAG: Tag

The associated tag for the type.

Note When implementing CHOICE types, this should be set to Tag::EOC and instead set the Self::TAG_TREE constant to contain all variants.

Provided Associated Constants§

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 IDENTIFIER: Identifier = Identifier::EMPTY

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

const IS_CHOICE: bool = false

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

Provided Methods§

fn is_present(&self) -> bool

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

Custom implementation is only used for OPTIONAL type.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
