Function rmp_serde::decode::from_slice

pub fn from_slice<'a, T>(input: &'a [u8]) -> Result<T, Error>
where
    T: Deserialize<'a>,

Deserialize a temporary scope-bound instance of type T from a slice, with zero-copy if possible.

Deserialization will be performed in zero-copy manner whenever it is possible, borrowing the data from the slice itself. For example, strings and byte-arrays won’t copied.

Errors

This conversion can fail if the structure of the Value does not match the structure expected by T. It can also fail if the structure is correct but T’s implementation of Deserialize decides that something is wrong with the data, for example required struct fields are missing.

Examples

use serde::Deserialize;

// Encoded `["Bobby", 8]`.
let buf = [0x92, 0xa5, 0x42, 0x6f, 0x62, 0x62, 0x79, 0x8];

#[derive(Debug, Deserialize, PartialEq)]
struct Dog<'a> {
   name: &'a str,
   age: u8,
}

assert_eq!(Dog { name: "Bobby", age: 8 }, rmp_serde::from_slice(&buf).unwrap());
