Struct Error 

pub struct Error<L> {
    pub expects: Expects,
    pub position: Range<L>,
}

Errors while parsing streams.

Fields

expects: Expects

Expected tokens.

position: Range<L>

The position where the error has occured.

Implementations

impl<L> Error<L>

pub fn rewindable(&self, pos: &L) -> bool

where L: PartialEq,

Checks if the parser can rewind input to pos discarding this error, or not.

Trait Implementations

impl<L: Clone> Clone for Error<L>

fn clone(&self) -> Error<L>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<L: Debug> Debug for Error<L>

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

Formats the value using the given formatter.

impl<L> Display for Error<L>

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

Formats the value using the given formatter.

impl<L: Debug> Error for Error<L>

Available on crate feature std only.

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<L: PartialEq> PartialEq for Error<L>

fn eq(&self, other: &Error<L>) -> 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.
