macro impl_Insertable! not found during build

[MattsSe]

Versions

• Rust: rustc 1.27.0-nightly (acd3871ba 2018-05-10)
• Diesel: 1.2.2
• Database: postgres
• Operating System macos high sierra 10.13.4

Problem Description

Can't compile structs that derive the Insertable trait, the Associations trait also seems to cause troubles. I checked various diesel version both on stable and nightly but received the same error.

What is the actual output?

 --> <proc-macro source code>:1:1
  |
1 | impl_Insertable ! { ( struct_name = Abc , table_name = abc , struct_ty = Abc , lifetimes = ( ) , ) , fields = [ { field_name:  id ,  column_name:  id ,  field_ty:  i32 ,  field_kind:  regular ,  inner_field_ty:  i32 ,  } { field_name:  name ,  column_name:  name ,  field_ty:  String ,  field_kind:  regular ,  inner_field_ty:  String ,  } ] , }
  | ^^^^^^^^^^^^^^^
