pub struct FromUtf8Error { /* private fields */ }Expand description
A possible error value when converting a String from a UTF-8 byte vector.
This type is the error type for the from_utf8 method on String. 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§
Source§impl FromUtf8Error
impl FromUtf8Error
Sourcepub fn into_utf8_lossy(self) -> String
🔬This is a nightly-only experimental API. (string_from_utf8_lossy_owned #129436)
pub fn into_utf8_lossy(self) -> String
string_from_utf8_lossy_owned #129436)Converts the bytes into a String lossily, substituting invalid UTF-8
sequences with replacement characters.
See String::from_utf8_lossy for more details on replacement of
invalid sequences, and String::from_utf8_lossy_owned for the
String function which corresponds to this function.
§Examples
1.0.0 · Sourcepub fn into_bytes(self) -> Vec<u8>
pub fn into_bytes(self) -> Vec<u8>
Returns the bytes that were attempted to convert to a String.
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.
