}Expand description
A trait for reading integers from a stream.
Allows reading signed and unsigned integers from 8 to 128 bits in either big or little endian byte order.
§Example
use pw_stream::{Cursor, ReadInteger};
let mut cursor = Cursor::new([0x3, 0x4, 0x5, 0x80]);
let value = cursor.read_u32_le().unwrap();
assert_eq!(value, 0x8005_0403);§Future Work
In order to allow for optimized non-generic implementations, there is
no blanket implementation over the crate::Read trait. An IntegerReader
adapter could be written to allow this functionality.
Required Methods§
sourcefn read_i8_le(&mut self) -> Result<i8>
fn read_i8_le(&mut self) -> Result<i8>
Reads a little-endian i8 returning it’s value or an Error.
Errors that may be returned are dependant on the underlying implementation.
sourcefn read_u8_le(&mut self) -> Result<u8>
fn read_u8_le(&mut self) -> Result<u8>
Reads a little-endian u8 returning it’s value or an Error.
Errors that may be returned are dependant on the underlying implementation.
sourcefn read_i8_be(&mut self) -> Result<i8>
fn read_i8_be(&mut self) -> Result<i8>
Reads a big-endian i8 returning it’s value or an Error.
Errors that may be returned are dependant on the underlying implementation.
sourcefn read_u8_be(&mut self) -> Result<u8>
