Trait that string-like specifications must implement.

Required Associated Types

type Data: Display

Type of data the specification is able to check for matches.

Required Associated Constants

const DATA_DESC: &'static str

Description of the kind of data this specification works on.

Required Methods

fn from_string(s: impl Into<String>) -> Res<Self>

Constructor from strings.

fn is_empty(&self) -> bool

True if the specification is empty, meaning it is ignored.

fn data_of_alloc(alloc: &Alloc) -> Arc<Vec<Self::Data>>

Extracts data from an allocation.

fn matches(&self, data: &Self::Data) -> bool

True if the input data is a match for this specification.

fn matches_anything(&self) -> bool

True if the specification matches a repetition of anything.

Implementors
