Enum encode_unicode::error::InvalidUtf8

pub enum InvalidUtf8 {
    FirstByte(InvalidUtf8FirstByte),
    NotAContinuationByte(usize),
    OverLong,
}

Reasons why a byte sequence is not valid UTF-8, excluding invalid codepoint. In sinking precedence.

Variants

FirstByte(InvalidUtf8FirstByte)

Something is wrong with the first byte.

NotAContinuationByte(usize)

The byte at index 1…3 should be a continuation byte, but dosesn’t fit the pattern 0b10xx_xxxx.

OverLong

There are too many leading zeros: it could be a byte shorter.

Decoding this could allow someone to input otherwise prohibited characters and sequences, such as “../”.

impl Eq for InvalidUtf8

impl Error for InvalidUtf8

fn description(&self) -> &'static 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

Returns Some if the error is a InvalidUtf8FirstByte.

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

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

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

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

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