There was a problem hiding this comment.
I don't know how. The solution so far is:
tag!(&[0xf0][..]) >>
version: be_u32 >>
motd: map!(rest, |bytes| bytes.to_vec() ) >>
verify!(value!(&motd), |motd: &Vec<_>| motd.len() <= 256) >> //MAX_MOTD_LENGTH
(BootstrapInfo { version, motd })

Why not:
motd: verify!(rest, |motd: &[u8]| motd.len() <= 256) >>
(BootstrapInfo { version, motd.to_vec() })
