Struct FromUtf8Error

pub struct FromUtf8Error<Bytes> { /* private fields */ }

A possible error value when converting a string from a UTF-8 byte vector.

This type is the error type for BumpString::from_utf8, MutBumpString::from_utf8 and BumpBox<str>::from_utf8. It is designed in such a way to carefully avoid reallocations: the into_bytes method will give back the byte vector that was used in the conversion attempt.

The Utf8Error type provided by std::str represents an error that may occur when converting a slice of u8s to a &str. In this sense, it’s an analogue to FromUtf8Error, and you can get one from a FromUtf8Error through the utf8_error method.

Implementations

impl<Bytes> FromUtf8Error<Bytes>

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

where Bytes: Deref<Target = [u8]>,

Returns a slice of u8s bytes that were attempted to convert to a String.

pub fn into_bytes(self) -> Bytes

Returns the bytes that were attempted to convert to a String.

pub fn utf8_error(&self) -> Utf8Error

Fetch a Utf8Error to get more details about the conversion failure.

The Utf8Error type provided by std::str represents an error that may occur when converting a slice of u8s to a &str. In this sense, it’s an analogue to FromUtf8Error. See its documentation for more details on using it.

Trait Implementations

impl<Bytes: Clone> Clone for FromUtf8Error<Bytes>

fn clone(&self) -> FromUtf8Error<Bytes>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Bytes: Debug> Debug for FromUtf8Error<Bytes>

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

Formats the value using the given formatter.

impl<Bytes> Display for FromUtf8Error<Bytes>

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

Formats the value using the given formatter.

impl<Bytes: Debug> Error for FromUtf8Error<Bytes>

Available on crate feature std only.

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.

impl<Bytes: PartialEq> PartialEq for FromUtf8Error<Bytes>

fn eq(&self, other: &FromUtf8Error<Bytes>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
