Expand description

The result of a macro expansion. The return values of the various methods are spliced into the AST at the callsite of the macro.

Provided Methods

Creates an expression.

Creates zero or more items.

Creates zero or more impl items.

Creates zero or more trait items.

Creates zero or more items in an extern {} block

Creates a pattern.

Creates zero or more statements.

By default this attempts to create an expression statement, returning None if that fails.
