Struct sixtyfps_compilerlib::expression_tree::BindingExpression

pub struct BindingExpression {
    pub expression: Expression,
    pub span: Option<SourceLocation>,
    pub priority: i32,
    pub analysis: RefCell<Option<BindingAnalysis>>,
}

The expression in the Element::binding hash table

Fields

expression: Expression

span: Option<SourceLocation>

The location of this expression in the source code

priority: i32

How deep is this binding declared in the hierarchy. When two binding are conflicting for the same priority (because of two way binding), the lower priority wins. The priority starts at 1, and each level of inlining adds one to the priority. 0 means the expression was added by some passes and it is not explicit in the source code

analysis: RefCell<Option<BindingAnalysis>>

The analysis information. None before it is computed

Implementations

impl BindingExpression

pub fn new_uncompiled(node: SyntaxNode) -> Self

pub fn new_with_span(expression: Expression, span: SourceLocation) -> Self

Methods from Deref<Target = Expression>

pub fn ty(&self) -> Type

Return the type of this property

pub fn visit(&self, visitor: impl FnMut(&Self))

Call the visitor for each sub-expression. (note: this function does not recurse)

pub fn visit_mut(&mut self, visitor: impl FnMut(&mut Self))

pub fn visit_recursive(&self, visitor: &mut dyn FnMut(&Self))

Visit itself and each sub expression recursively

pub fn is_constant(&self) -> bool

pub fn try_set_rw(&mut self) -> bool

Try to mark this expression to a lvalue that can be assigned to.

Return true if the expression is a “lvalue” that can be used as the left hand side of a = or += or similar
