Documentation

data Selector

Selectors are used for projecting from various components. Each selector has an option spec to specify the shape of the thing that is being selected. Currently, there is no surface syntax for list selectors, but they are used during the desugaring of patterns.

Constructors

TupleSel Int (Maybe Int)

Zero-based tuple selection. Optionally specifies the shape of the tuple (one-based).

RecordSel Ident (Maybe [Ident])

Record selection. Optionally specifies the shape of the record.

ListSel Int (Maybe Int)

List selection. Optionally specifies the length of the list.
