Module parser 

DSL parsing for instruction definitions.

This module parses .chipi files (or source strings) into an intermediate representation. The parser handles:

• Decoder configuration (name, width, bit order)
• Type aliases for custom field types
• Instruction definitions with fixed bit patterns and variable fields

Bit ranges are converted from DSL notation (where the order depends on bit_order config) to hardware notation (LSB=0) during validation.

Functions

dsl_to_hardware

Convert DSL bit positions to hardware (LSB=0) positions with unit support.

parse

Parse DSL source text into a decoder definition.

parse_file

Parse a .chipi file from a path, resolving include directives relative to its directory.

parse_file_with_deps

Parse a .chipi file and return both the definition and the set of all resolved file paths (input + includes). Useful for cargo:rerun-if-changed.
