Struct widestring::error::Utf32Error

pub struct Utf32Error { /* private fields */ }

Errors which can occur when attempting to interpret a sequence of u32 as UTF-32.

Implementations

impl Utf32Error

pub fn index(&self) -> usize

Returns the index in the given string at which the invalid UTF-32 value occurred.

pub fn into_vec(self) -> Option<Vec<u32>>

Consumes this error, returning the underlying vector of values which generated the error in the first place.

If the sequence that generated the error was a reference to a slice instead of a Vec, this will return None.

Trait Implementations

impl Clone for Utf32Error

fn clone(&self) -> Utf32Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Utf32Error

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

Formats the value using the given formatter.

impl Display for Utf32Error

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

Formats the value using the given formatter.

impl Error for Utf32Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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 self, req: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.
