Struct rtlola_parser::ast::RtLolaAst

pub struct RtLolaAst {
    pub imports: Vec<Import>,
    pub constants: Vec<Rc<Constant>>,
    pub inputs: Vec<Rc<Input>>,
    pub outputs: Vec<Rc<Output>>,
    pub mirrors: Vec<Rc<Mirror>>,
    pub trigger: Vec<Rc<Trigger>>,
    pub type_declarations: Vec<TypeDeclaration>,
    pub next_node_id: RefCell<NodeId>,
}

The root of a RTLola specification, consisting of stream and trigger declarations. Each declaration contains the id of the Ast node, a span, and declaration-specific components.

Ast Node Kinds

• Import represents an import statement for a module.
• Constant represents a constant stream.
• Input represents an input stream.
• Output represents an output stream.
• Mirror represents mirror streams, a syntactic sugar for an output stream.
• Trigger represents a trigger declaration.
• TypeDeclaration captures a user given type declaration.

Related Data Structures

• A NodeId is a unique identifier given to every node of the RtLolaAst
• A Span links an Ast node to its code location.

Implementations

impl RtLolaAst

pub fn clone_deep(&self) -> RtLolaAst

Creates a deep clone of the Ast. I.e. clones the underlying data not the RCs.

Trait Implementations

impl Clone for RtLolaAst

fn clone(&self) -> RtLolaAst

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RtLolaAst

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

Formats the value using the given formatter.

impl Default for RtLolaAst

fn default() -> RtLolaAst

Returns the “default value” for a type.
