Function write_bin_len

src/encode.rs:666–679

Encodes and attempts to write the most efficient binary array length implementation to the given write, returning the marker used. This function is useful when you want to get full control for writing the data itself, for example, when using non-blocking socket. # Errors This function will return `ValueWriteError` on any I/O error occurred while writing either the marker or the data, except the

(wr: &mut W, len: u32)

/// This function will return `ValueWriteError` on any I/O error occurred while writing either the
