Errors produced by ISLE.

Variants

IoError

Fields

error: Arc<Error>

The underlying I/O error.

context: String

The context explaining what caused the I/O error.

An I/O error.

ParseError

Fields

msg: String

The error message.

src: Source

The input ISLE source.

span: Span

The location of the parse error.

The input ISLE source has a parse error.

TypeError

Fields

msg: String

The error message.

src: Source

The input ISLE source.

span: Span

The location of the type error.

The input ISLE source has a type error.

OverlapError

Fields

msg: String

The error message.

rules: Vec<(Source, Span)>

The locations of all the rules that overlap. When there are more than two rules present, the first rule is the one with the most overlaps (likely a fall-through wildcard case).

The rules mentioned overlap in the input they accept.

Errors(Vec<Error>)

Multiple errors.

Implementations

impl Error

pub fn from_io(error: Error, context: impl Into<String>) -> Self

Create a isle::Error from the given I/O error and context.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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 From<Vec<Error, Global>> for Error

fn from(es: Vec<Error>) -> Self

Converts to this type from the input type.
