Struct ShapeMismatchError 

pub struct ShapeMismatchError {
    pub expected: &'static Shape,
    pub actual: &'static Shape,
}

Error returned when materializing a HeapValue to the wrong type.

This is separate from ReflectError because HeapValue operations don’t have path context - they operate on already-constructed values.

Fields

expected: &'static Shape

The shape that was expected (the target type).

actual: &'static Shape

The shape that was actually found (the HeapValue’s shape).

Trait Implementations

impl Clone for ShapeMismatchError

fn clone(&self) -> ShapeMismatchError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeMismatchError

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

Formats the value using the given formatter.

impl Display for ShapeMismatchError

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

Formats the value using the given formatter.

impl Error for ShapeMismatchError

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.
