Module utils 

Utilities used in this crate which can also be generally useful downstream.

Modules

zeroize

Securely zero memory with a simple trait (Zeroize) built on stable Rust primitives which guarantee the operation will not be “optimized away”.

Structs

BudgetedReader

A reader wrapper that enforces a byte budget during deserialization.

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.

HexParseError

Defines errors which can occur during parsing of hexadecimal strings.

Traits

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.

Serializable

Defines how to serialize Self into bytes.

Functions

assume_init_vec^⚠

Converts a fully-initialized Vec<MaybeUninit<T>> into Vec<T>.

bytes_to_elements_exact

Converts bytes to field elements with validation.

bytes_to_elements_with_padding

Converts a sequence of bytes into vector field elements with padding. This guarantees that no two sequences or bytes map to the same sequence of field elements.

bytes_to_hex_string

Renders an array of bytes as hex into a String.

bytes_to_packed_u32_elements

Converts bytes to field elements using u32 packing in little-endian format.

elements_to_bytes

Converts field elements to raw byte representation.

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.

hex_to_bytes

Parses a hex string into an array of bytes of known size.

padded_elements_to_bytes

Converts a sequence of padded field elements back to the original bytes.

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.

word_to_hex

Converts a Word into hex.
