Language.Rust.Data.Position

Everything to do with describing a position or a contiguous region in a file.

Positions in files

data Position

A position in a source file. The row and column information is kept only for its convenience and human-readability. Analogous to the information encoded in a cursor.

Constructors

Position

Fields

• absoluteOffset :: !Int

  absolute offset the source file.

• row :: !Int

  row (line) in the source file.

• col :: !Int

  column in the source file.

class Located a where

Describes nodes that can be located - their span can be extracted from them. In general, we expect that for a value constructed as Con x y z where Con is an arbitrary constructor

(spanOf x <> spanOf y <> spanOf z) `subsetOf` spanOf (Con x y z) == True
