Struct InptError

pub struct InptError<'s> { /* private fields */ }

Provides information about parsing errors.

Implementations

impl<'s> InptError<'s>

pub fn expected_regex(re: &'static str, found: &'s str) -> Self

pub fn expected_regex_at_start(re: &'static str) -> Self

pub fn expected_regex_at_end(re: &'static str) -> Self

pub fn expected_lit(lit: &'static impl Debug, found: &'s str) -> Self

pub fn expected_lit_at_start(lit: &'static impl Debug) -> Self

pub fn expected_lit_at_end(lit: &'static impl Debug) -> Self

pub fn expected<T>(found: &'s str) -> Self

pub fn expected_at_start<T>() -> Self

pub fn expected_at_end<T>() -> Self

pub fn expected_regex_group(index: usize) -> Self

pub fn expected_from_str<T>(found: &'s str) -> Self

pub fn recursion_at_start<T>() -> Self

impl<'s> InptError<'s>

pub fn row_col(&self) -> Option<Range<(usize, usize)>>

Returns the range of zero-indexed (row,column) pairs indicating the location in the input where the error occured, if any could be determined.

pub fn unparsable_text(&self) -> Option<&'s str>

Returns the portion of the input text which caused the error, if any could be determined.

pub fn annotated( &self, output: impl Write, force_styling: Option<bool>, ) -> Result<()>

Pretty-prints the error trace into the given writer.

pub fn annotated_stdout(&self, source: &str) -> Result<()>

Pretty-prints the error trace into stdout. If the filename or other input name is known, provide it as source.

pub fn annotated_stderr(&self, source: &str) -> Result<()>

Pretty-prints the error trace into stderr. If the filename or other input name is known, provide it as source.

Trait Implementations

impl<'s> Clone for InptError<'s>

fn clone(&self) -> InptError<'s>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'s> Debug for InptError<'s>

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

Formats the value using the given formatter.

impl<'a> Display for InptError<'a>

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

Formats the value using the given formatter.

impl Error for InptError<'static>

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.
