Crate winter_utils

This crate contains utility traits, functions, and macros used by other crates of Winterfell STARK prover and verifier.

Modules

iterators

Components needed for parallel iterators.

Macros

batch_iter_mut

Applies a procedure to the provided slice either in a single thread or multiple threads based on whether concurrent feature is enabled.

iter

Returns either a regular or a parallel iterator depending on whether concurrent feature is enabled.

iter_mut

Returns either a regular or a parallel mutable iterator depending on whether concurrent feature is enabled.

Structs

ReadAdapter

An adapter of ByteReader to any type that implements std::io::Read

SliceReader

Implements ByteReader trait for a slice of bytes.

Enums

DeserializationError

Defines errors which can occur during deserialization.

Traits

AsBytes

Defines a zero-copy representation of Self as a sequence of bytes.

ByteReader

Defines how primitive values are to be read from Self.

ByteWriter

Defines how primitive values are to be written into Self.

Deserializable

Defines how to deserialize Self from bytes.

Randomizable

Defines how Self can be read from a sequence of random bytes.

Serializable

Defines how to serialize Self into bytes.

Functions

flatten_slice_elements

Transmutes a slice of n arrays each of length N, into a slice of N * n elements.

flatten_vector_elements

Transmutes a vector of n arrays each of length N, into a vector of N * n elements.

group_slice_elements

Transmutes a slice of n elements into a slice of n / N elements, each of which is an array of N elements.

transpose_slice

Transposes a slice of n elements into a matrix with N columns and n/N rows.

uninit_vector^⚠

Returns a vector of the specified length with un-initialized memory.
