Enum StateError 

pub enum StateError {
    InvalidShape {
        expected: Vec<usize>,
        got: Vec<usize>,
    },
    InvalidData(String),
    InvalidSize {
        expected: usize,
        got: usize,
    },
}

Error type for state validation failures.

Returned by validation logic when a state’s shape, contents, or element count do not match the expectations of the calling code.

Examples

use rlevo_core::state::StateError;

let err = StateError::InvalidShape {
    expected: vec![4, 4],
    got: vec![4, 3],
};
assert!(err.to_string().contains("Invalid shape"));

let err = StateError::InvalidData("NaN in position field".into());
assert!(err.to_string().contains("NaN in position field"));

let err = StateError::InvalidSize { expected: 16, got: 12 };
assert!(err.to_string().contains("Invalid size"));

Variants

InvalidShape

Shape dimensions do not match expectations.

Fields

expected: Vec<usize>

got: Vec<usize>

InvalidData(String)

Data contents violate invariants.

InvalidSize

Total element count does not match expectations.

Fields

expected: usize

got: usize

Trait Implementations

impl Clone for StateError

fn clone(&self) -> StateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateError

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

Formats the value using the given formatter.

impl Display for StateError

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

Formats the value using the given formatter.

impl Error for StateError

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 StateError

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