Module mayda::utility [−] [src]

Contains constants, enums, traits and functions used by all of the encoding types provided by the mayda crate.

Traits

Access	A trait for indexing an encoded vector. Similar to but less convenient than `Index`. `Index::index()` returns a reference, but an encoded vector type must give ownership of the returned value to the caller.
AccessInto	A trait for indexing a range of an encoded vector. Writes the result into the slice provided. Similar to but less convenient than `Index`.
Bits	Indicates that the bitwise representation of the type is known to `mayda`. Intended to be implemented only for the primitive integer types. Mainly used as a bound on the `Encode` trait.
Encode	Indicates that the type can be encoded and decoded by `mayda`.

select_m	A modified version of the Floyd-Rivest algorithm with fewer comparisions and fewer swaps, specialized for the case of slices with length < 500. The modifications may not be known in the literature. Intended to be used to find the median of a block.
words_for_bits	Returns number of words required to store the given number of bits. A word is 32 bits long.
