Module eval

Expand description

Column resolution, expressions, aggregators, topological sort.

Pure computation — no IO, no CLI, no serde. Used by CLI engine and all bindings.

ExprEnv
ParentCtx: Per-table context for reconstructing a parent row’s generation environment. Stored inside Fk and FkDeref variants. Zero-initialized at parse time; filled by finalize_fk_columns before generation.

check_expr_types
column_domain_hash: Compute the domain hash for a single column, including alias detection. Use this when reproducing a parent column’s hash for FK recomputation.

generate_from_columns
generate_records_from_specs: Parse field specs, resolve columns, generate records. Returns (column_names, records). Used by all bindings.

resolve_expr_types
resolve_field_specs: Parse field spec strings (CLI-style) into resolved columns with topo sort. Handles aliases (name=field:mod), expressions (total=price*qty), aggregators (running=amount:sum).
spec_display_name: Display name for a field spec: name:upper → name_upper, phone:e164 → phone_e164.
