Function `be_i8`

fn be_i8<I, E: ParseError<I>>() -> impl Parser<I, Output = i8, Error = E>
where
    I: Input<Item = u8>

Recognizes a signed 1 byte integer.

Streaming version: Will return Err(nom::Err::Incomplete(_)) if there is not enough data.

# use nom::{Err, error::ErrorKind, Needed, Parser};
