Implementations

impl ValueError

pub fn unsupported<'v, T, V: StarlarkValue<'v> + ?Sized>( _left: &V, op: &str ) -> Result<T>

Helper to create an OperationNotSupported error.

pub fn unsupported_with<'v, T, V: StarlarkValue<'v> + ?Sized>( _left: &V, op: &str, right: Value<'_> ) -> Result<T>

Helper to create an OperationNotSupported error.

Trait Implementations

impl Debug for ValueError

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

Formats the value using the given formatter.

impl Display for ValueError

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

Formats the value using the given formatter.

impl Error for ValueError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<ValueError> for Error

fn from(e: ValueError) -> Self

Converts to this type from the input type.
