Trait TransferCounter 

pub trait TransferCounter:
    Copy
    + Ord
    + Debug
    + Display {
    const ZERO: Self;

    // Required method
    fn checked_add_chunk(self, chunk_len: usize) -> Option<Self>;
}

Integer type used to count cumulative transfer bytes.

The default counter is usize. Use u64 or u128 when a stream may legitimately contain more bytes than fit in a pointer-sized count.

Required Associated Constants

const ZERO: Self

Zero bytes.

Required Methods

fn checked_add_chunk(self, chunk_len: usize) -> Option<Self>

Add a chunk length to the current count.

Returns None when the new cumulative count cannot be represented by this counter type.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
