Function sqlite_varint::read_varint

pub fn read_varint(bytes: &[u8]) -> (i64, usize)

Reads a slice of bytes from the start assuming it is a varint. Gives back the varint as i64 and the amount of bytes the varint was big.

Example

use sqlite_varint::read_varint;
// Small positive integer values take little place
assert_eq!((1, 1), read_varint(&vec![0b00000001]));

// Negative values will always take 9 bytes.
// Note that the vector is 10 bytes long.
assert_eq!((-1, 9), read_varint(&vec![0xff; 10]));
