Trait Attribute

Source 
pub trait Attribute<V>: AttributeName + TryFromMeta<V, Metadata = <V as SynVersion>::Attribute>
where
    V: SynVersion,
{
    // Provided method
    fn from_attrs(
        location: Span,
        attrs: Vec<<V as SynVersion>::Attribute>,
    ) -> Result<Self, Vec<<V as SynVersion>::Error>> { ... }
}
Expand description

Represents a struct that can be deserialized from Syn attributes.

Provided Methods§

Source

fn from_attrs( location: Span, attrs: Vec<<V as SynVersion>::Attribute>, ) -> Result<Self, Vec<<V as SynVersion>::Error>>

Creates a deserialized attribute from a list of Syn attributes.

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.
