Am I right that using Zig's new declaration literals, you can't override the defaults when initializing the variable?
var gpa = std.heap.GeneralPurposeAllocator(.{}){
.backing_allocator = ...,
};
vs
var gpa: std.heap.GeneralPurposeAllocator(.{}) = .init;
gpa.backing_allocator = ...; // is this the only way?

yeah, .init here just reference a declaration made inside of the struct, nothing more. it’s not like a special init syntax

Aren't you able to pass .{ .thread_safe = false } into the config argument of the gpa?
gaunt depot
err..ya, my mistake
inland lagoon
.init should then be fine to use
gaunt depot
What about backing_allocator, for example, though ?
I changed the original post/question
inland lagoon
Then yeah, I think you'll need to either initialize with the init decl and then change the backing allocator or initialize each field yourself
lethal notch
yeah basically
not being able to do this is one of the reasons for decl literals existing
inland lagoon
Sinon is correct that there's nothing special about .init, it's just a constant declared on GPA

not being able to do this is one of the reasons for decl literals existing
it means you can't incorrectly initialize something on accident
