Various simple utilities.

Modules§

apply_to_chunks: Split an iterator into small arrays and apply func to each.
assume
branch_hint: Try to force Rust to emit a branch. Example:
convert_vec^⚠: Converts a vector of one type to one of another type.
indices_arr: Returns [0, ..., N - 1].
log2_ceil_u64
log2_ceil_usize: Computes ceil(log_2(n)).
log2_strict_usize: Computes log_2(n)
pretty_name: Return a String containing the name of T but with all the crate and module prefixes removed.
reverse_bits
reverse_bits_len
reverse_slice_index_bits: Permutes arr such that each index is mapped to its reverse in binary. If the whole array fits in fast cache, then the trivial algorithm is cache friendly. Also, if T is really big, then the trivial algorithm is cache-friendly, no matter the size of the array.
transpose_vec
