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 Diagnostic for Error

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan>>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn related(&self) -> Option<Box<dyn Iterator<Item = &dyn Diagnostic>>>

Additional related Diagnostics.

fn code(&'a self) -> Option<Box<dyn Display + 'a, Global>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or Enums will work just fine.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by [ReportHandler]s to change the display format of this diagnostic.

fn help(&'a self) -> Option<Box<dyn Display + 'a, Global>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn url(&'a self) -> Option<Box<dyn Display + 'a, Global>>

URL to visit for a more detailed explanation/help about this Diagnostic.

impl Display for Error

fn fmt(&self, __formatter: &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 backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Vec<Error, Global>> for Error

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

Converts to this type from the input type.
