Trait AttributeAccess 

pub trait AttributeAccess {
    // Required methods
    fn has_attribute<T: FromAttribute + PartialEq<T>>(
        &self,
        attrib: T,
    ) -> Result<bool>;
    fn get_attribute<T: FromAttribute>(&self) -> Result<Option<T>>;
}

Bring useful methods to access attributes of an element.

Required Methods

fn has_attribute<T: FromAttribute + PartialEq<T>>( &self, attrib: T, ) -> Result<bool>

Check to see if has the given attribute. See FromAttribute for more information.

note: Will immediately return Err(_) on the first error T returns.

fn get_attribute<T: FromAttribute>(&self) -> Result<Option<T>>

Returns the first attribute that returns Some(Self). See FromAttribute for more information.

note: Will immediately return Err(_) on the first error T returns.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
