impl WhitelistedAttributes

pub fn parse_arg_value(&mut self, arg: &MetaNameValue) -> Result<(), Error>

pub fn filter_attr(&self, attrs: Vec<Attribute>) -> Vec<Attribute>

Returns the filtered input vector of whitelisted attributes. All not whitelisted attributes are removed.

impl Default for WhitelistedAttributes

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for WhitelistedAttributes

fn eq(&self, other: &WhitelistedAttributes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
