Module signal 

Deterministic numeric signal contracts and their loadable runtime library.

The SDK intentionally exposes the reusable transform boundary, not the crate’s implementation modules or cookbook helpers.

Structs

SignalNumbersLib

Loadable runtime library exporting signal_transform_symbol.

Stride

Logical selection of values from a physical one-dimensional buffer.

TransformPlan

Reusable, fully explicit transform plan.

TransformReport

Auditable execution facts for an in-memory or blocked transform.

TransformResources

Caller-declared memory budget and external block granularity.

Enums

Direction

Direction in which a transform plan is applied.

LengthPolicy

Relationship between the logical plan length and available input values.

Normalization

Scaling convention applied by a forward/inverse transform pair.

PaddingPolicy

Values used when LengthPolicy::Pad extends an input.

PlacementPolicy

Whether execution writes a distinct result or overwrites caller storage.

SignConvention

Complex-exponential sign convention.

SignalBuffer

Owned transform result in canonical tensor storage.

SignalError

Error returned when a transform plan or signal buffer is invalid.

SignalView

Borrowed transform input.

SpectrumPacking

Packing of a real FFT spectrum.

TransformKind

Mathematical transform selected by a plan.

TransformPrecision

Cell representation used by a multidimensional transform.

Functions

call_signal_transform

Calls signal/transform with evaluated symbol options, a length, and a real list or list of complex (real imag) pairs.

reference_dft

Computes the direct, unnormalized complex DFT definition.

signal_transform_symbol

Symbol of the Lisp-facing transform operation (signal/transform).

transform

Executes an out-of-place transform into canonical tensor storage.

transform_in_place

Executes a same-representation transform into mutable caller storage.
