Struct rtlola_frontend::ast::InvokeSpec

pub struct InvokeSpec {
    pub target: Expression,
    pub condition: Option<Expression>,
    pub is_if: bool,
    pub id: NodeId,
    pub span: Span,
}

An AST node representing the declaration of an invoke condition of a parametrized stream

Fields

target: Expression

The expression defining the parameter instances. If the stream has more than one parameter, the expression needs to return a tuple, with one element for each parameter

condition: Option<Expression>

An additional condition for the creation of an instance, i.e., an instance is only created if the condition is true If 'is_true' is false, this component is assigned to 'None'

is_if: bool

A flag to describe if the invoke declaration contains an additional condition

id: NodeId

The ID of the node in the AST

span: Span

The span in the specification declaring the invoke declaration
