Struct hltas::read::Error

pub struct Error<'a> {
    pub input: &'a str,
    pub context: Option<Context>,
    /* private fields */
}

.hltas parsing error.

Fields

input: &'a str

Remaining input at the point of failure.

context: Option<Context>

Semantic meaning of the parsing error.

Implementations

impl Error<'_>

pub fn line(&self) -> usize

Returns the line number on which the error has occurred.

Trait Implementations

impl<'a> Clone for Error<'a>

fn clone(&self) -> Error<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Error<'a>

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

Formats the value using the given formatter.

impl Display for Error<'_>

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

Formats the value using the given formatter.

impl Error for Error<'_>

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

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, demand: &mut Demand<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

impl<'a, E> FromExternalError<&'a str, E> for Error<'a>

fn from_external_error(input: &'a str, kind: ErrorKind, _e: E) -> Self

Creates a new error from an input position, an ErrorKind indicating the wrapping parser, and an external error

impl<'a> ParseError<&'a str> for Error<'a>

fn from_error_kind(input: &'a str, kind: ErrorKind) -> Self

Creates an error from the input position and an ErrorKind

fn append(_input: &'a str, _kind: ErrorKind, other: Self) -> Self

Combines an existing error with a new one created from the input position and an ErrorKind. This is useful when backtracking through a parse tree, accumulating error context on the way

fn from_char(input: &'a str, c: char) -> Self

Creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

Combines two existing errors. This function is used to compare errors generated in various branches of alt.

impl<'a> PartialEq<Error<'a>> for Error<'a>

fn eq(&self, other: &Error<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
