This type is available if Syn is built with the "derive" or "full" feature.

A type contained within invisible delimiters.

This type is available if Syn is built with the "derive" or "full" feature.

Indication that a type should be inferred by the compiler: _.

This type is available if Syn is built with the "derive" or "full" feature.

A macro in the type position.

This type is available if Syn is built with the "derive" or "full" feature.

Tokens in type position not interpreted by Syn.

This type is available if Syn is built with the "derive" or "full" feature.

Methods

impl Type
[src]

In some positions, types may not contain the + character, to disambiguate them. For example in the expression 1 as T, T may not contain a + character.

This parser does not allow a +, while the default parser does.
