sourcepub fn const_kind(&self) -> ConstContext
pub fn const_kind(&self) -> ConstContext
Returns the kind of const context this Item
represents (const
, static
, etc.).
Panics if this Item
is not const.

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
