Expand description

Represents the declaration of a function directly parsed from source syntax.

Fields§

§name: String§subtype: FunctionSubtype§schema: Schema

Untyped schema

§resolved_schema: Head

Resolved schema after typechecking is stored here, otherwise “”.

§merge: Option<GenericExpr<Head, Leaf>>§cost: Option<DefaultCost>§unextractable: bool§internal_hidden: bool

Hidden functions are excluded from print-size output. Used for internal tables generated by proof production.

§internal_let: bool

Globals are desugared to functions, with this flag set to true. This is used by visualization to handle globals differently.

§span: Span§term_constructor: Option<String>

For view tables in proof encoding: the constructor to use for building terms from the first n-1 children during extraction.
