Struct bump_scope::FromUtf8Error

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

A possible error value when converting a MutBumpString from a MutBumpVec<u8> or a BumpBox<str> from a BumpBox<[u8]> where the bytes are UTF-8.

This type is the error type for the MutBumpString::from_utf8 and BumpBox<[u8]>::into_boxed_str. 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.
