Module library 

Standard Polydat function-node library + sampling primitives + library-internal support.

• Function-node modules (arithmetic, string, hash, …): the 250+ built-in crate::ast::PolydatNode implementations workload authors compose into kernels.
• polydat_nodes::sampling: alias tables, LUT interpolation, ICD — variate-sampling building blocks consumed by distribution-emitting nodes (weighted, probability, etc.).
• support: library-internal infrastructure (support::cache, support::audit) used by nodes like vectors for caching dataset handles and diagnosing data-source mismatches.

Modules

assertions

Type and value assertion nodes.

context

Context state nodes: non-deterministic, session-scoped values.

convert

Type conversion nodes.

datafile

Data file nodes: ordinal-based access to CSV, JSONL, and text files.

diagnostic

Diagnostic and debugging nodes.

exactly_one

exactly_one_value — explicit unwrap of a unary structural body (SRD-66 §“Surface 4”).

fixed

Fixed value and value-list nodes across fundamental types.

format

Printf-style formatting node.

identity

Identity and constant nodes.

json

JSON construction, serialization, and manipulation nodes.

log_levels

log_debug / log_info / log_warn / log_error — pass-through logging node functions (SRD-66 §“Surface 5”).

polyfill

Polyfill edge adapters covering every cell of the type matrix from polydat/docs/design/type_system.md §3 that has a sensible conversion.

polyfill_128

Polyfill edge adapters for the 128-bit integer types (u128/i128) — cranelift I128 under both signedness interpretations (polydat/docs/design/type_system_alignment.md §8.1).

polyfill_complete

Matrix-completion adapters — the boundary (class-B) conversions that fill every meaningful (from, to) cell the §3 catalog had left as ·. Generated by paste!-driven macros so the ~130 trivial transforms aren’t hand-written; each is still a real #[polydat_node] (the SRD-80b authoring path), so they JIT and register exactly like the hand-written adapters.

polyfill_narrow

Polyfill edge adapters for the narrow cranelift scalar widths (u8/i8/u16/i16/f16) added by the full-cranelift type alignment (polydat/docs/design/type_system_alignment.md §8.1).

register_view

The register view retag adapter the assembler inserts between register ports of different lane typings, and the register-port predicate it keys on (type_system_alignment.md §8.4 layer 2).

support

Support utilities used by Polydat function nodes.

tile_render

The tile nodes (SRD 114 §6, §7.1).

vectors

Vector dataset access nodes via the vectordata crate.

Functions

debug_nodes_enabled

Env-gated debug-level diagnostic for selection / matching nodes.
