This library provides an implementation of bytes::BufMut to count the size of a resulting buffer.

[dependencies]
bufsize = "1.0"

Example

use bufsize::SizeCounter;
use bytes::BufMut;

pub struct DataStructure;

impl DataStructure {
    pub fn serialize<B: BufMut>(&self, buf: &mut B) {
        let name = "DataStructure";
        buf.put_u8(name.len() as u8);
        buf.put_slice(name.as_bytes());
        buf.put_u32_le(9999);
        buf.put_f32_le(1.0);
    }
}

fn main() {
    let mut sizecount = SizeCounter::new();
    DataStructure.serialize(&mut sizecount);

    let mut buffer = Vec::with_capacity(sizecount.size());
    DataStructure.serialize(&mut buffer);

    assert_eq!(sizecount.size(), buffer.len());
}
