Enum ScanErrorKind

pub enum ScanErrorKind {
    LiteralMismatch,
    Syntax(&'static str),
    SyntaxNoMessage,
    ExpectedEnd,
    Float(ParseFloatError),
    Int(ParseIntError),

}

Indicates the kind of error that occurred during scanning.

Variants

LiteralMismatch

Failed to match a literal pattern term.

Syntax(&'static str)

General syntax error.

SyntaxNoMessage

General syntax error.

Due to Rust issue #26448, some scanners which want to return a Syntax error cannot.

ExpectedEnd

Expected end-of-input.

Float(ParseFloatError)

Floating point parsing failed.

Int(ParseIntError)

Integer parsing failed.

Io(Error)

An IO error occurred.

Other(Box<dyn Error>)

Some other error occurred.

Implementations

impl ScanErrorKind

pub fn from_other<E: Into<Box<dyn Error>>>(err: E) -> Self

Construct an Other error from some generic error value.

Trait Implementations

impl Debug for ScanErrorKind

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

Formats the value using the given formatter.

impl Display for ScanErrorKind

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

Formats the value using the given formatter.

impl Error for ScanErrorKind

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn description(&self) -> &str

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

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

Returns 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.
