Usage

API

Encode

• encode<T, I>(iterable: I) -> Result<Vec<u8>, Box<dyn Error>>
• Bounds -> T: IntoBytes, I: IntoIterator<Item = T>

let list: Vec<&[u8]> = vec![&[1,2,3], &[4,5,6], &[7,8,9]];
let encoded = astro_format::encode(list).unwrap();

Decode

• decode<'a, T, B>(buffer: &'a B) -> Result<Vec<T>, Box<dyn std::error::Error>>
• Bounds -> T: TryFromBytes<'a>, B: AsRef<[u8]>

let decoded: Vec<&[u8]> = astro_format::decode(&encoded).unwrap();

IntoBytes

The IntoBytes trait provides a mechanism to convert various data types into a vector of bytes (Vec). It is a versatile trait for serialization purposes, facilitating the conversion of primitive data types, strings, and even characters into a byte representation.

pub trait IntoBytes {
    fn into_bytes(&self) -> Vec<u8>;
}

TryInto

The TryFromBytes trait is designed for converting a slice of bytes (&[u8]) back into various data types. It's particularly useful in contexts where data serialized as bytes needs to be deserialized back into its original or a usable form.

pub trait TryFromBytes<'a>: Sized {
    fn try_from_bytes(value: &'a [u8]) -> Result<Self, Box<dyn std::error::Error>>;
}

IntoBytes & TryInto Type Support

• Unsigned and Signed integers
• String and Str
• Vectors and Slices of Bytes
• Characters
