pub enum Error {
    Diagnostic(Box<Diagnostic>),
    Io {

        source: Error,
    },
    Config(String),
    Message(String),
}

The crate’s top-level error.

Variants

Diagnostic(Box<Diagnostic>)

Io

Fields

path: PathBuf

source: Error

Config(String)

A configuration problem (e.g. missing --out).

Message(String)

A free-form internal error that is not tied to a source location.

Implementations

impl Error

pub fn io(path: impl Into<PathBuf>, source: Error) -> Self

Wrap a path-tagged I/O error.

pub fn config(msg: impl Into<String>) -> Self

Build a configuration error.

pub fn message(msg: impl Into<String>) -> Self

Build a free-form error.

pub fn diagnostic(&self) -> Option<&Diagnostic>

Borrow the wrapped diagnostic, if this is one.

Trait Implementations

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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 From<Diagnostic> for Error

fn from(d: Diagnostic) -> Self

Converts to this type from the input type.
