Function bitcoin::blockdata::script::write_scriptint

pub fn write_scriptint(out: &mut [u8; 8], n: i64) -> usize

Encodes an integer in script(minimal CScriptNum) format.

Writes bytes into the buffer and returns the number of bytes written.

Note that write_scriptint/read_scriptint do not roundtrip if the value written requires more than 4 bytes, this is in line with Bitcoin Core (see CScriptNum::serialize).
