https://metacpan.org/pod/FFI::C::Struct

This is ambiguous. Synopsis describe FFI::C::StructDef, methods do same.

What is FFI::C::Struct?

[KES777]

Here: https://metacpan.org/pod/FFI::C::StructDef#trim_string1

I do not work with C so do not understand what is fixed-length strings and how they trimmed.
Would be nice to see usecase

[KES777]

Here: https://metacpan.org/pod/FFI::C::Struct

At other module's synopsis you use bundle and pass parameter $ffi here is missed. This is unclear why here it is missed and what is the difference

Here I found that we may pass or miss this parameter. This is unclear which one will be created. And unclear the difference

[KES777]

Here an example could be improved:

my $definition =  FFI::C::StructDef->new( class => 'User::Struct::Class', ... );
my $instance = $definition->new; 
my $instance = User::Struct::Class->new; # same

[KES777]

Did not find an example how to use array members.

Please, mention this here

  FFI::C::StructDef->new(
    $ffi,
    nullable =>  1,
    name     =>  'SDL_RendererInfo',
    class    =>  'SDL2::RendererInfo',
    members  =>  [
      name                =>  'string',
      flags               =>  'uint32',
      num_texture_formats =>  'uint32',
      texture_formats     =>  'uint32[16]',
      max_texture_width   =>  'int',
      max_texture_height  =>  'int',
    ],
  );
