Enum Predicate 

pub enum Predicate {
    AttrEquals {
        attr: String,
        value: String,
    },
    Contains {
        attr: String,
        substr: String,
    },
    Position(usize),
    AttrExists {
        attr: String,
    },
}

A predicate inside square brackets [...].

Variants

AttrEquals

[@attr='value'] — exact attribute match.

Fields

attr: String

Attribute name.

value: String

Expected value.

Contains

[contains(@attr, 'substr')] — attribute substring match.

Fields

attr: String

Attribute name.

substr: String

Substring to find.

Position(usize)

[position()=N] — 1-based position among siblings of same type.

AttrExists

[@attr] — attribute existence check.

Fields

attr: String

Attribute name.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl PartialEq for Predicate

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