Struct bsn1::IdRef

pub struct IdRef { /* fields omitted */ }

IdRef is a wrapper of [u8] represents Identifier.

This struct is Unsized , and user will usually use a reference to it.

Implementations

impl IdRef

pub unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self

Provides a reference from bytes without any sanitize. bytes must not include any extra octets.

If it is not sure whether bytes is valid octets as an identifer or not, use TryFrom implementation instead.

Safety

The behavior is undefined if the format of bytes is not right.

Examples

use bsn1::{ClassTag, Id, IdRef, PCTag};

let id = Id::new(ClassTag::Universal, PCTag::Primitive, 0);
