[−][src]Type Definition byteio::Result
type Result<T> = Result<T, Error>;
A specialized Result
type for byteio
operations.
This type alias is broadly used across byteio
for operations that may
produce an error, that is, overflow the underlying buffer.
As with std::io::Result
, it is not recommended to import
this type directly and shadow core::result::Result
,
but instead to use byteio::Result
to make it easier to distinguish.
Examples
Trying to decode a string from raw bytes:
use core::str::{self, Utf8Error}; use byteio::WriteBytes; fn decode_str(buf: &[u8]) -> Result<&str, Utf8Error> { str::from_utf8(buf) } fn main() -> byteio::Result<()> { let mut buf = [0; 5]; (&mut buf[..]).try_write_exact(b"hello")?; match decode_str(&buf) { Ok(s) => println!("str from utf8 success!"), Err(e) => println!("str from utf8 failure: {}", e), } Ok(()) }
