Re-exports§

ColMatrix
CsrMatrix: Compressed Sparse Row matrix mapping row indices to variable-length data.
DenseIdMap: A dense mapping from ID to ID.
DisplayHex: A display helper for formatting a slice of bytes as hex with different options using Rust’s builtin format language
IndexVec: A dense vector indexed by ID types.
ReadAdapter: An adapter of ByteReader to any type that implements std::io::Read

CsrValidationError: Errors that can occur during CSR validation.
HexParseError: Defines errors which can occur during parsing of hexadecimal strings.
IndexedVecError: Error returned when too many items are added to an IndexedVec.

Idx: A trait for u32-backed, 0-based IDs.
IntoBytes
LookupByIdx: A trait for looking up values by ID.
Matrix: A generic trait for two-dimensional matrix-like data structures.
ToElements
ToHex: This trait represents a value that can be converted to a string of hexadecimal digits which represent the raw byte encoding of that value.

bound_into_included_u64: Converts and parses a Bound into an included u64 value.
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.
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.
hash_string_to_word: Hashes the provided string using the BLAKE3 hash function and converts the resulting digest into a Word.
hex_to_bytes: Parses a hex string into an array of bytes of known size.
packed_u32_elements_to_bytes: Converts u32-packed field elements back to bytes in little-endian format.
range: Returns a Range initialized with the specified start and with end set to start + len.
to_hex: Construct a String containing the hexadecimal representation of bytes
uninit_vector^⚠: Returns a vector of the specified length with un-initialized memory.
