Function from_slice

pub fn from_slice<T: BorshDeserialize>(v: &[u8]) -> Result<T>

Deserializes an object from a slice of bytes.

Example

use borsh::{BorshDeserialize, BorshSerialize, from_slice, to_vec};

/// derive is only available if borsh is built with `features = ["derive"]`
#[derive(BorshSerialize, BorshDeserialize, PartialEq, Debug)]
struct MyStruct {
   a: u64,
   b: Vec<u8>,
}

let original = MyStruct { a: 10, b: vec![1, 2, 3] };
let encoded = to_vec(&original).unwrap();
let decoded = from_slice::<MyStruct>(&encoded).unwrap();
assert_eq!(original, decoded);
