Struct EvalBlockError 

pub struct EvalBlockError { /* private fields */ }

Errors resulting from Block::evaluate().

Implementations

impl EvalBlockError

pub fn block(&self) -> &Block

Returns the block whose evaluation failed.

pub fn to_placeholder(&self) -> EvaluatedBlock

Convert this error into an EvaluatedBlock which represents that an error has occurred.

This block is fully opaque and as inert to game mechanics as currently possible.

Trait Implementations

impl Clone for EvalBlockError

fn clone(&self) -> EvalBlockError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EvalBlockError

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

Formats the value using the given formatter.

impl Display for EvalBlockError

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

Formats the value using the given formatter.

impl Error for EvalBlockError

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 Hash for EvalBlockError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for EvalBlockError

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