Struct rslint_core::groups::errors::NoExtraBooleanCast [−][src]
pub struct NoExtraBooleanCast {
pub enforce_for_logical_operands: bool,
}
Expand description
Disallow unnecessary boolean casts.
In contexts where expression will be coerced to a Boolean
(e.g. if
),
casting to a boolean (using !!
or Boolean(expr)
) is unnecessary.
Invalid Code Examples
if (!!foo) {}
while (!!foo) {}
var foo = !!!bar;
var foo = Boolean(!!bar);
Fields
enforce_for_logical_operands: bool
If this option is true
, this rule will also check for unnecessary boolean
cast inside logical expression, which is disabled by default.
Implementations
Trait Implementations
Check an individual node in the syntax tree.
You can use the match_ast
macro to make matching a node to an ast node easier.
The reason this uses nodes and not a visitor is because nodes are more flexible,
converting them to an AST node has zero cost and you can easily traverse surrounding nodes.

Check the root of the tree one time.
This method is guaranteed to only be called once.
The root’s kind will be either SCRIPT
or MODULE
.
