Enum ThinError 

pub enum ThinError {
    ExpectedError,
}

A thin error type that indicates an expected failure without any reason.

In SPARQL, many operations can fail. For example, because the input value had a different data type. However, these errors are expected and are part of the query evaluation. As all of these “expected” errors are treated equally in the query evaluation, we do not need to store a reason.

Implementations

impl ThinError

pub fn expected<T>() -> Result<T, ThinError>

Creates a result with a ThinError.

Trait Implementations

impl Clone for ThinError

fn clone(&self) -> ThinError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThinError

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Display for ThinError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Error for ThinError

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 PartialEq for ThinError

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