Term

Enum Term 

Source
pub enum Term {
    Id(Id),
    Selector(Selector),
}
Expand description

Term.

Terms can either be identifiers or selectors, both of which are convertible into Selector. By providing Id, the term represents an exact match on identifiers, whereas providing a Selector allows for more complex matching criteria.

Variants§

§

Id(Id)

Identifier.

§

Selector(Selector)

Selector.

1.0.0 · Source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
Source§

impl ToSpecificity for Term

Source§

fn to_specificity(&self) -> Specificity

Computes the specificity of the term.

§Examples
use zrx_id::expression::Term;
use zrx_id::selector;
use zrx_id::specificity::ToSpecificity;

// Create term and compute specificity
let term = Term::from(selector!(location = "**/*.md")?);
assert_eq!(term.to_specificity(), (0, 1, 1, 3).into());
Source§

impl TryFrom<Term> for Selector

Source§

fn try_from(term: Term) -> Result<Self>

Attempts to create a selector from a term.

§Examples
use zrx_id::expression::Term;
use zrx_id::{Id, Selector};

// Create selector from identifier
let id: Id = "zri:file:::docs:index.md:".parse()?;
let selector: Selector = Term::from(id).try_into()?;
