Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. pgx.StructArgs converts exported struct fields into a QueryRewriter that rewrites named SQL parameters (@field) into positional placeholders ($1, $2, ...)
  2. pgx.StructArgs extracts parameter names from db struct tags and ignores fields tagged with db:"-"
  3. pgx.StructArgs falls back to Go field names when db struct tags are omitted
  4. pgx.StructArgs accepts both struct values and pointers to structs
  5. pgx.StructArgs reuses positional placeholders when the same parameter is referenced multiple times in SQL
  6. pgx.StrictStructArgs enforces strict parameter matching and returns an error when SQL references missing fields or when struct contains unused fields
  7. sample helpers provide typed query rewriting, parameter extraction, and SQL argument construction using pgx.StructArgs
