Enum TriangulationMetadataField 

#[non_exhaustive]
pub enum TriangulationMetadataField {
    Timeslices,
    Dimension,
}

Identifies the CDT triangulation metadata field that failed validation.

Use this with CdtError::InvalidTriangulationMetadata to distinguish invalid metadata fields without relying on display text.

Examples

use causal_triangulations::prelude::errors::{CdtError, TriangulationMetadataField};
use causal_triangulations::prelude::triangulation::CdtTopology;
use std::assert_matches;

let metadata_error = CdtError::InvalidTriangulationMetadata {
    field: TriangulationMetadataField::Timeslices,
    topology: CdtTopology::Toroidal,
    provided_value: "2".to_string(),
    expected: "at least three time slices".to_string(),
};

assert_matches!(
    metadata_error,
    CdtError::InvalidTriangulationMetadata {
        field: TriangulationMetadataField::Timeslices,
        ..
    }
);

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Timeslices

Number of time slices recorded in triangulation metadata.

Dimension

Dimensionality recorded in triangulation metadata.

Trait Implementations

impl Clone for TriangulationMetadataField

fn clone(&self) -> TriangulationMetadataField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriangulationMetadataField

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

Formats the value using the given formatter.

impl Display for TriangulationMetadataField

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

Formats the value using the given formatter.

impl Hash for TriangulationMetadataField

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 TriangulationMetadataField

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