Module std::bool

The bool module contains useful code to help work with boolean values.

A quick summary:

Trait implementations for `bool`

Implementations of the following traits:

All of the standard comparison functions one would expect: and, eq, or, and more.

Also, a few conversion functions: to_bit and to_str.

Finally, some inquiries into the nature of truth: is_true and is_false.

all_values	Iterates over all truth values, passing them to the given block.
and	Conjunction of two boolean values.
implies	Implication between two boolean values.
is_false	Is a given boolean value false?
is_true	Is a given boolean value true?
not	Negation of a boolean value.
or	Disjunction of two boolean values.
to_bit	Convert a `bool` to a `u8`.
xor	An 'exclusive or' of two boolean values.
