Module format 

Format detection, parsing and emission.

Both directions cross the IR boundary here and nowhere else: parse yields a Value, emit takes one. The conversions themselves live in crate::value.

Enums

Format

v1 ships JSON and TOML only. Adding a format is one arm of these matches; removing one is a breaking change.

SourceName

Which input a parse error came from. Names an input being read, so there is no variant for --set: a bad --set expression is rejected by PathLeaf during argument parsing, long before anything reaches here.

Functions

emit

Converts the merged IR into format and serializes it.

parse

Parses one layer into the merge IR.
