Function write 

pub fn write(
    type_: &str,
    subtype: &str,
    params: &[(&str, &str)],
    out: &mut impl Sink,
) -> Result<(), WriteError>

Writes type/subtype and then ; name=value for each pair, values as a token when they are one and as a quoted string otherwise.

Errors

WriteError::NotToken for a type, subtype, or name that is not a token (or is *); WriteError::DuplicateName for two parameters with the same name (ASCII case-insensitive), which parsers refuse; WriteError::Forbidden for a control byte in a value; WriteError::Full. Nothing is written on error when the sink reports its room.

Examples

use parse_net::{media, SliceSink};

let mut buf = [0u8; 64];
let mut out = SliceSink::new(&mut buf);
media::write("multipart", "form-data", &[("boundary", "a b")], &mut out)?;
assert_eq!(out.written(), b"multipart/form-data; boundary=\"a b\"");
