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.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
