Struct TargetElem

pub struct TargetElem { /* private fields */ }

This element exists solely to host the target style chain field. It is never constructed and not visible to users.

Implementations

impl TargetElem

pub fn new() -> TargetElem

Create a new instance of the element.

pub fn with_target(self, target: Target) -> TargetElem

Builder-style setter for the target field.

pub fn push_target(&mut self, target: Target)

Setter for the target field.

pub fn target(&self, styles: StyleChain<'_>) -> Target

The compilation target.

pub fn target_in(styles: StyleChain<'_>) -> Target

Access the target field in the given style chain.

pub fn set_target(target: Target) -> Property

Create a style property for the target field.

Trait Implementations

impl Capable for TargetElem

fn vtable(capability: TypeId) -> Option<NonNull<()>>

Get the pointer to the vtable for the given capability / trait.

impl Clone for TargetElem

fn clone(&self) -> TargetElem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Construct for TargetElem

fn construct( engine: &mut Engine<'_>, args: &mut Args, ) -> Result<Content, EcoVec<SourceDiagnostic>>

Construct an element from the arguments.

impl Debug for TargetElem

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

Formats the value using the given formatter.

impl Fields for TargetElem

type Enum = Fields

An enum with the fields of the element.

fn has(&self, id: u8) -> bool

Whether the element has the given field set.

fn field(&self, id: u8) -> Result<Value, FieldAccessError>

Get the field with the given field ID.

fn field_with_styles( &self, id: u8, styles: StyleChain<'_>, ) -> Result<Value, FieldAccessError>

Get the field with the given ID in the presence of styles.

fn field_from_styles( id: u8, styles: StyleChain<'_>, ) -> Result<Value, FieldAccessError>

Get the field with the given ID from the styles.

fn materialize(&mut self, styles: StyleChain<'_>)

Resolve all fields with the styles and save them in-place.

fn fields(&self) -> Dict

Get the fields of the element.

impl Hash for TargetElem

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

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 TargetElem

fn into_value(self) -> Value

Cast this type into a value.

impl NativeElement for TargetElem

fn data() -> &'static NativeElementData

Get the element data for the native Rust element.

fn elem() -> Element

where Self: Sized,

Get the element for the native Rust element.

fn pack(self) -> Content

where Self: Sized,

Pack the element into type-erased content.

impl PartialEq for TargetElem

fn eq(&self, other: &TargetElem) -> 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 Repr for TargetElem

fn repr(&self) -> EcoString

Return the debug representation of the value.

impl Set for TargetElem

fn set( engine: &mut Engine<'_>, args: &mut Args, ) -> Result<Styles, EcoVec<SourceDiagnostic>>

Parse relevant arguments into style properties for this element.
