Enum Selector 

pub enum Selector {
    Elem(Element, Option<SmallVec<[(u8, Value); 1]>>),
    Location(Location),
    Label(Label),
    Regex(Regex),
    Can(TypeId),
    Or(EcoVec<Self>),
    And(EcoVec<Self>),
    Before {
        selector: Arc<Self>,

        inclusive: bool,
    },
    Within {
        selector: Arc<Self>,
        ancestor: Arc<Self>,
    },
}

A filter for selecting elements within the document.

Variants

Elem(Element, Option<SmallVec<[(u8, Value); 1]>>)

Matches a specific type of element.

If there is a dictionary, only elements with the fields from the dictionary match.

Location(Location)

Matches the element at the specified location.

Label(Label)

Matches elements with a specific label.

Regex(Regex)

Matches text elements through a regular expression.

Can(TypeId)

Matches elements with a specific capability.

This is not exposed, but used internally.

Or(EcoVec<Self>)

Matches if any of the subselectors match.

And(EcoVec<Self>)

Matches if all of the subselectors match.

Before

Matches all matches of selector before end.

Fields

selector: Arc<Self>

end: Arc<Self>

inclusive: bool

After

Matches all matches of selector after start.

Fields

selector: Arc<Self>

start: Arc<Self>

inclusive: bool

Within

Matches all matches of selector that are strictly within ancestor.

This is not yet exposed, but used internally.

Fields

selector: Arc<Self>

ancestor: Arc<Self>

Implementations

impl Selector

pub fn text(text: &str) -> StrResult<Self>

Define a simple text selector.

pub fn regex(regex: Regex) -> StrResult<Self>

Define a regex selector.

pub fn can<T: ?Sized + Any>() -> Self

Define a simple Selector::Can selector.

pub fn matches(&self, target: &Content, styles: Option<StyleChain<'_>>) -> bool

Whether the selector matches for the target.

impl Selector

pub fn construct(target: Selector) -> Selector

Turns a value into a selector.

pub fn or(self, others: Vec<Selector>) -> Selector

Selects all elements that match this or any of the other selectors.

pub fn and(self, others: Vec<Selector>) -> Selector

Selects all elements that match this and all of the other selectors.

pub fn before(self, end: LocatableSelector, inclusive: bool) -> Selector

Returns a modified selector that will only match elements that occur before the first match of end.

pub fn after(self, start: LocatableSelector, inclusive: bool) -> Selector

Returns a modified selector that will only match elements that occur after the first match of start.

pub fn within(self, ancestor: LocatableSelector) -> Selector

Returns a modified selector that will only match elements that are contained within any elements matching the ancestor selector.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selector

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

Formats the value using the given formatter.

impl From<Location> for Selector

fn from(value: Location) -> Self

Converts to this type from the input type.

impl FromValue for Selector

fn from_value(value: Value) -> HintedStrResult<Self>

Try to cast the value into an instance of Self.

impl Hash for Selector

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 IntoValue for Selector

fn into_value(self) -> Value

Cast this type into a value.

impl NativeScope for Selector

fn constructor() -> Option<&'static NativeFuncData>

The constructor function for the type, if any.

fn scope() -> Scope

Get the associated scope for the type.

impl NativeType for Selector

const NAME: &'static str = "selector"

The type’s name.

fn data() -> &'static NativeTypeData

fn ty() -> Type

Get the type for the native Rust type.

impl PartialEq for Selector

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

impl Reflect for Selector

fn input() -> CastInfo

Describe what can be cast into this value.

fn output() -> CastInfo

Describe what this value can be cast into.

fn castable(value: &Value) -> bool

Whether the given value can be converted to T.

fn error(found: &Value) -> HintedString

Produce an error message for an unacceptable value type.

impl Repr for Selector

fn repr(&self) -> EcoString

Return the debug representation of the value.

impl StructuralPartialEq for Selector
