pub fn write_integer(out: &mut Vec<u8>, value_be: &[u8])Expand description
Append a DER INTEGER tag-length-value.
value_be is the unsigned big-endian magnitude; leading zeros
are stripped, then a 0x00 is re-prepended if the first content
byte has its high bit set (positive-integer disambiguation).
ยงPanics
Panics if value_be is empty.
