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 “../”.

Trait Implementations

impl Clone for InvalidUtf8

fn clone(&self) -> InvalidUtf8

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for InvalidUtf8

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

Formats the value using the given formatter.

impl Display for InvalidUtf8

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

Formats the value using the given formatter.

impl Error for InvalidUtf8

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.

fn description(&self) -> &'static str

👎Deprecated since 1.42.0: use the Display impl or to_string()

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

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

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 From<InvalidUtf8> for InvalidUtf8Array

fn from(error: InvalidUtf8) -> InvalidUtf8Array

Converts to this type from the input type.

impl From<InvalidUtf8> for InvalidUtf8Slice

fn from(error: InvalidUtf8) -> InvalidUtf8Slice

Converts to this type from the input type.

impl From<InvalidUtf8FirstByte> for InvalidUtf8

fn from(error: InvalidUtf8FirstByte) -> InvalidUtf8

Converts to this type from the input type.

impl PartialEq for InvalidUtf8

fn eq(&self, other: &InvalidUtf8) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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