Struct dfir_lang::graph::OperatorInstance

pub struct OperatorInstance {
    pub op_constraints: &'static OperatorConstraints,
    pub input_ports: Vec<PortIndexValue>,
    pub output_ports: Vec<PortIndexValue>,
    pub singletons_referenced: Vec<Ident>,
    pub generics: OpInstGenerics,
    pub arguments_pre: Punctuated<Expr, Comma>,
    pub arguments_raw: TokenStream,
}

Meta-data relating to operators which may be useful throughout the compilation process.

This data can be generated from the graph, but it is useful to have it readily available pre-computed as many algorithms use the same info. Stuff like port names, arguments, and the OperatorConstraints for the operator.

Because it is derived from the graph itself, there can be “cache invalidation”-esque issues if this data is not kept in sync with the graph.

Fields

op_constraints: &'static OperatorConstraints

Name of the operator (will match OperatorConstraints::name).

input_ports: Vec<PortIndexValue>

Port values used as this operator’s input.

output_ports: Vec<PortIndexValue>

Port values used as this operator’s output.

singletons_referenced: Vec<Ident>

Singleton references within the operator arguments.

generics: OpInstGenerics

Generic arguments.

arguments_pre: Punctuated<Expr, Comma>

Arguments provided by the user into the operator as arguments. I.e. the a, b, c in -> my_op(a, b, c) -> .

These arguments do not include singleton postprocessing codegen. Instead use ops::WriteContextArgs::arguments.

arguments_raw: TokenStream

Unparsed arguments, for singleton parsing.
