Struct abi_stable::std_types::string::FromUtf8Error

pub struct FromUtf8Error { /* private fields */ }

Error that happens when attempting to convert an RVec<u8> into an RString.

Example

use abi_stable::std_types::RString;

let err = RString::from_utf8(vec![0, 0, 0, 255]).unwrap_err();

assert_eq!(err.as_bytes(), &[0, 0, 0, 255])

Implementations

impl FromUtf8Error

pub fn into_bytes(self) -> RVec<u8>

Unwraps this error into the bytes that failed to be converted into an RString.

Example

use abi_stable::std_types::{RString, RVec};

let bytes: RVec<u8> = vec![72, 111, 95, 95, 95, 95, 95, 99, 107, 255].into();

let err = RString::from_utf8(bytes.clone()).unwrap_err();

assert_eq!(err.into_bytes(), bytes);

pub fn as_bytes(&self) -> &[u8]

Gets access to the bytes that failed to be converted into an RString.

Example

use abi_stable::std_types::RString;

let bytes = vec![99, 114, 121, 115, 116, 97, 108, 255];

let err = RString::from_utf8(bytes.clone()).unwrap_err();

assert_eq!(err.as_bytes(), &bytes[..]);

pub fn error(&self) -> Utf8Error

Gets a Utf8Error with information about the conversion error.

Example

use abi_stable::std_types::RString;

let err = RString::from_utf8(vec![0, 0, 255]).unwrap_err();

assert_eq!(err.error().valid_up_to(), 2);

Trait Implementations

impl Debug for FromUtf8Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FromUtf8Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for FromUtf8Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
