Function borsh::object_length

pub fn object_length<T>(value: &T) -> Result<usize>
where
    T: BorshSerialize + ?Sized,

Serializes an object without allocation to compute and return its length

Example

use borsh::BorshSerialize;

/// derive is only available if borsh is built with `features = ["derive"]`
#[derive(BorshSerialize)]
struct A {
    tag: String,
    value: u64,
};

let a = A { tag: "hello".to_owned(), value: 42 };

assert_eq!(8, borsh::object_length(&12u64).unwrap());
assert_eq!(17, borsh::object_length(&a).unwrap());
