Bool

bool is Move's primitive type for boolean true and false values.

Literals

Literals for bool are either true or false.

Operations

Logical

bool supports three logical operations:

Syntax	Description	Equivalent Expression
`&&`	short-circuiting logical and	`p && q` is equivalent to `if (p) q else false`
`\|\|`	short-circuiting logical or	`p \|\| q` is equivalent to `if (p) true else q`
`!`	logical negation	`!p` is equivalent to `if (p) false else true`

Control Flow

bool values are used in several of Move's control-flow constructs:

if (bool) { ... }
while (bool) { .. }
assert!(bool, u64)

Ownership

As with the other scalar values built-in to the language, boolean values are implicitly copyable, meaning they can be copied without an explicit instruction such as copy.
