Expand description

An item definition.

Fields§

§attrs: AttrVec§id: NodeId§span: Span§vis: Visibility§ident: Ident

The name of the item. It might be a dummy name in case of anonymous items.

§kind: K§tokens: Option<LazyAttrTokenStream>

Original tokens this item was parsed from. This isn’t necessarily available for all items, although over time more and more items should have this be Some. Right now this is primarily used for procedural macros, notably custom attributes.

Note that the tokens here do not include the outer attributes, but will include inner attributes.

Implementations§

Return the span that encompasses the attributes.

Returns a copy of the value. Read more
Performs copy-assignment from source. Read more
Formats the value using the given formatter. Read more
This is true if this HasAttrs might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes. Read more

Mutably borrows from an owned value. Read more

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The resulting type after obtaining ownership.

The type returned in the event of a conversion error.
Performs the conversion.
The type returned in the event of a conversion error.
Performs the conversion.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
