Crate serde_asn1_der 

serde_asn1_der

Welcome to serde_asn1_der 🎉

This crate implements an ASN.1-DER subset for serde based upon asn1_der.

The following types are supported:

• bool: The ASN.1-BOOLEAN-type
• u8, u16, u32, u64, u128, usize: The ASN.1-INTEGER-type
• (), Option: The ASN.1-NULL-type
• &[u8], Vec<u8>: The ASN.1-OctetString-type
• &str, String: The ASN.1-UTF8String-type
• And everything sequence-like combined out of this types

With the serde_derive-crate you can derive Serialize and Deserialize for all non-primitive elements:

use serde_derive::{ Serialize, Deserialize };

#[derive(Serialize, Deserialize)] // Now our struct supports all DER-conversion-traits
struct Address {
    street: String,
    house_number: u128,
    postal_code: u128,
    state: String,
    country: String
}

#[derive(Serialize, Deserialize)] // Now our struct supports all DER-conversion-traits too
struct Customer {
    name: String,
    e_mail_address: String,
    postal_address: Address
}

Example

use serde_asn1_der::{ to_vec, from_bytes };
use serde_derive::{ Serialize, Deserialize };

#[derive(Serialize, Deserialize)]
struct TestStruct {
    number: u8,
    #[serde(with = "serde_bytes")]
    vec: Vec<u8>,
    tuple: (usize, ())
}

fn main() {
    let plain = TestStruct{ number: 7, vec: b"Testolope".to_vec(), tuple: (4, ()) };
    let serialized = to_vec(&plain).unwrap();
    let deserialized: TestStruct = from_bytes(&serialized).unwrap();
}

AnyObject

This crate also offers a type-erased AnyObject-trait, that allows you to use Box<dyn AnyObject> instead of a specific type. To enable AnyObject, use the "any"-feature.

Structs

VecBacking

A newtype wrapper around a &'a mut Vec<u8> that implements Sink and Into<&'a [u8]>

Enums

SerdeAsn1DerError

Functions

from_bytes

Deserializes T from bytes

from_reader

Copies the first top-level object from reader into backing and deserializes it from there

from_source

Copies the first top-level object from source into backing and deserializes it from there

to_sink

Serializes value to buf and returns the amount of serialized bytes

to_vec

Serializes value

to_writer

Serializes value to writer and returns the amount of serialized bytes
