Struct std::ffi::FromVecWithNulError [−][src]
pub struct FromVecWithNulError { /* fields omitted */ }
An error indicating that a nul byte was not in the expected position.
The vector used to create a CString
must have one and only one nul byte,
positioned at the end.
This error is created by the CString::from_vec_with_nul
method.
See its documentation for more.
Examples
#![feature(cstring_from_vec_with_nul)] use std::ffi::{CString, FromVecWithNulError}; let _: FromVecWithNulError = CString::from_vec_with_nul(b"f\0oo".to_vec()).unwrap_err();Run
Implementations
impl FromVecWithNulError
[src]
impl FromVecWithNulError
[src]pub fn as_bytes(&self) -> &[u8]ⓘ
[src]
Returns a slice of u8
s bytes that were attempted to convert to a CString
.
Examples
Basic usage:
#![feature(cstring_from_vec_with_nul)] use std::ffi::CString; // Some invalid bytes in a vector let bytes = b"f\0oo".to_vec(); let value = CString::from_vec_with_nul(bytes.clone()); assert_eq!(&bytes[..], value.unwrap_err().as_bytes());Run
pub fn into_bytes(self) -> Vec<u8>ⓘ
[src]
Returns the bytes that were attempted to convert to a CString
.
This method is carefully constructed to avoid allocation. It will consume the error, moving out the bytes, so that a copy of the bytes does not need to be made.
Examples
Basic usage:
#![feature(cstring_from_vec_with_nul)] use std::ffi::CString; // Some invalid bytes in a vector let bytes = b"f\0oo".to_vec(); let value = CString::from_vec_with_nul(bytes.clone()); assert_eq!(bytes, value.unwrap_err().into_bytes());Run
