Is there a way to define different methods on a struct at comptime depending on the type?
like
pub fn foo(comptime T: type) type {
return struct {
if (T == u8) {
pub fn bar() u32 {
return 1;
}
pub fn baz() u32 {
return 2;
}
} else {
pub fn bar() f32 {
return 1.0
}
pub fn baz() f32 {
return 2.0;
}
}
}
}

pub const bar = switch(T) {
u8 => bar_u8,
else => bar_other,
};
fn bar_u8() u32 {}
fn bar_other() f32 {}
what if I want a method to not be implemented at all on a struct depending on T?

f32 => @compileError("Not supported for T == f32")
will only compile error if they reference it
or you could do
pub usingnamespace switch(T) {
u8 => struct {
fn bar() u32 {}
},
f32 => struct {},
else => struct {
fn bar() u32 {}
},
};
