Function bitconv::to_int64

pub fn to_int64<T: BitConvEndian>(data: &[u8], start_index: usize) -> i64

Returns a 64-bit signed integer converted from eight bytes at a specified position in a byte array.

The to_int64 function converts the bytes from index start_index to start_index + 7 to a i64 value.

Example

use bitconv::{
    endian::{Big, Little}, to_int64
};

let buffer = [15, 0, 0, 128, 16, 39, 240, 216, 241, 255, 127];
assert_eq!(-1019801265028202496, to_int64::<Little>(&buffer, 1));
assert_eq!(140806877927665, to_int64::<Big>(&buffer, 1));
