Struct ScanError

pub struct ScanError { /* private fields */ }

An error that occurred while scanning.

Implementations

impl ScanError

pub fn new(loc: Marker, info: String) -> ScanError

Create a new error from a location and an error string.

pub fn new_str(loc: Marker, info: &str) -> ScanError

Convenience alias for string slices.

pub fn marker(&self) -> &Marker

Return the marker pointing to the error in the source.

pub fn info(&self) -> &str

Return the information string describing the error that happened.

Trait Implementations

impl Clone for ScanError

fn clone(&self) -> ScanError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScanError

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

Formats the value using the given formatter.

impl Display for ScanError

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

Formats the value using the given formatter.

impl Error for ScanError

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 ScanError

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