Structs
A wrapper type to ensure that the parser handles outer attributes correctly.
When we parse outer attributes, we need to ensure that we capture tokens
for the attribute target. This allows us to perform cfg-expansion on
a token stream before we invoke a derive proc-macro.
Stores span information about a closure.
SeqSep 🔒
A sequence separator.
Enums
Controls how we capture tokens. Capturing can be expensive,
so we try to avoid performing capturing in cases where
we will never need an

Indicates a range of tokens that should be replaced by
the tokens in the provided vector. This is used in two
places during token collection:
