Struct Error 

pub struct Error {
    pub cause: ErrorCause,
    pub location: Location,
}

Explanation of an expansion failure.

Fields

cause: ErrorCause

location: Location

Implementations

impl Error

pub fn to_report(&self) -> Report<'_>

Returns a report for the error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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, __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<'a> From<&'a Error> for Report<'a>

Converts the error into a report by calling Error::to_report.

fn from(error: &'a Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl Handle for Error

Prints an error message and returns a divert result indicating a non-zero exit status.

This implementation handles the error by printing an error message to the standard error and returning Divert::Interrupt(Some(ExitStatus::ERROR)). If the ErrExit option is set, Divert::Exit(Some(ExitStatus::ERROR)) is returned instead.

Note that other POSIX-compliant implementations may use different non-zero exit statuses.

async fn handle(&self, env: &mut Env) -> Result

Handles the argument error.

impl PartialEq for Error

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