Struct ordered_varint::Signed

pub struct Signed(_);

A signed integer value.

This type encodes values in the range -2.pow(123)..2.pow(123) by using the first 5 bits to denote a signed byte length. This length ranges from -15..=15. The number of bytes read is always absolute, but the sign of the length is used to determine the overall sign of the encoded value. The remaining 3 bits of the first byte and any additional bytes are then used to store the integer in big-endian encoding.
