Implementations

impl Stmt

pub fn sort_key(&self) -> StmtSortKey

Get the sort key for the statement.

This allows a collection of statements to be reordered into:

• Uses
• Items
• Macro expansions.
• The rest, expressions, local decl, etc…

Note that the sort implementation must be stable, to make sure that intermediate items are not affected.
