Enum Utf8ParserError

pub enum Utf8ParserError {
    InvalidByte(u8),
    InvalidChar(u32),
    UnexpectedStartByte(u8),
    UnexpectedContinuationByte(u8),
    OverlongEncoding,
}

Error type used for the utf8-parser crate

Variants

InvalidByte(u8)

Encountered an invalid byte. This is a byte that’s invalid no matter the context.

InvalidChar(u32)

Found a code point that’s not valid UTF-8.

UnexpectedStartByte(u8)

Found a start byte in an unexpected place

UnexpectedContinuationByte(u8)

Found a continuation byte in an unexpected place

OverlongEncoding

Represented a valid code point in a longer form than necessary.

From Wikipedia:

The standard specifies that the correct encoding of a code point uses only the minimum number of bytes required to hold the significant bits of the code point. Longer encodings are called overlong and are not valid UTF-8 representations of the code point. This rule maintains a one-to-one correspondence between code points and their valid encodings, so that there is a unique valid encoding for each code point. This ensures that string comparisons and searches are well-defined.

Trait Implementations

impl Clone for Utf8ParserError

fn clone(&self) -> Utf8ParserError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Utf8ParserError

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

Formats the value using the given formatter.

impl Display for Utf8ParserError

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

Formats the value using the given formatter.

impl Error for Utf8ParserError

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 Utf8ParserError

fn eq(&self, other: &Utf8ParserError) -> 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.
