Implementations

impl ElementSource

pub fn to_ir(&self, limits: &ResourceLimits) -> Result<ElementIr>

Validates and converts one static, self-contained source element to IR.

This compact boundary is suitable for programmatic and tool-driven Canvas additions. Components, props, slots, named or conditional styles, bindings, conditions, and repeats require the complete crate::Compiler pipeline and are rejected here.

Trait Implementations

impl Clone for ElementSource

fn clone(&self) -> ElementSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ElementSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ElementSource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ElementSource

fn eq(&self, other: &ElementSource) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Serialize for ElementSource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
