Hello if been browsing the zig compiler and i noticed a couple of times the usage of const Self = @This(); bit not within a struct but just unscoped im a file. What does this mean?

Eg src/arch/x86-64/CodeGen.zig line 794

all files in zig are structs
CodeGen.zig is actually a struct definition
it’s meant to be imported as
const CodeGen = @import(“CodeGen.zig”) and used as a struct

#

so @This() works just as youd expect

I'm actually really surprised no object oriented language (that I know of) has this feature. It seems perfectly made for them

#

Well, GDScript kind of does it

#const Self = @This();
