Struct Error 

pub struct Error { /* private fields */ }

An error from a basis-tasks operation: what went wrong, in one line.

Implementations

impl Error

pub fn is_invalid_reference(&self) -> bool

Whether this is exactly that: a bad argument no amount of waiting fixes, as opposed to an ordinary operational failure. A host mapping this crate’s errors onto its own vocabulary — basis-cli’s “usage” exit code (ADR-0015), for one — reads this rather than the message text.

pub fn hint(&self) -> Option<&Hint>

The next step this error names, when it names one unambiguously — see Hint.

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

Formats the value using the given formatter.

impl Eq for Error

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<&str> for Error

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<String> for Error

fn from(message: String) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
