Enum gtk4::ConstraintVflParserError

#[non_exhaustive]
pub enum ConstraintVflParserError {
    Symbol,
    Attribute,
    View,
    Metric,
    Priority,
    Relation,
    // some variants omitted
}

Domain for VFL parsing errors.

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.

Symbol

Invalid or unknown symbol

Attribute

Invalid or unknown attribute

View

Invalid or unknown view

Metric

Invalid or unknown metric

Priority

Invalid or unknown priority

Relation

Invalid or unknown relation
