Macro nom::length_bytes
[−]
[src]
macro_rules! length_bytes { ($i:expr, $submac:ident!( $($args:tt)* )) => { ... }; ($i:expr, $f:expr) => { ... }; }
length_bytes!(&[T] -> IResult<&[T], nb>) => &[T] -> IResult<&[T], &[T]>
Gets a number from the first parser, then extracts that many bytes from the
remaining stream
Example
named!(with_length, length_bytes!( be_u8 )); let r = with_length(&b"\x05abcdefgh"[..]); assert_eq!(r, Ok((&b"fgh"[..], &b"abcde"[..])));
