Enum Utf8Error

pub enum Utf8Error {
    InvalidCodepoint(u32),
    InvalidEncoding(Vec<u8>),
    OverlongEncoding(Vec<u8>),
    Truncated(Vec<u8>),
}

The errors that can occur when decoding UTF-8.

Variants

InvalidCodepoint(u32)

The codepoint is not a valid Unicode codepoint.

InvalidEncoding(Vec<u8>)

The encoding is not valid UTF-8.

OverlongEncoding(Vec<u8>)

The encoding is “overlong,” e.g., a two-byte UTF-8 encoding of a codepoint that could be encoded in a single byte. This is not allowed in UTF-8 for security reasons.

Truncated(Vec<u8>)

The character was truncated when being decoded.

Trait Implementations

impl Debug for Utf8Error

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

Formats the value using the given formatter.

impl Display for Utf8Error

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

Formats the value using the given formatter.

impl Error for Utf8Error

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 PartialEq for Utf8Error

fn eq(&self, other: &Utf8Error) -> 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.
