#How to compare string types in a more lenient way?

So I have this code but the type system is too strict, I want to allow all *const [n:0]u8 but it only works when you specify a length and the sentinel value like *const [3:0]u8 in this case.

Compiler Explorer - Zig (zig 0.10.0)

const std = @import("std");
const print = std.debug.print;
const Allocator = std.mem.Allocator;
const ArenaAllocator = std.heap.ArenaAllocator;

// sentinel pointer to T = T
// pointer to T = []T
// slice to T = []T
// array of T = [N]T or [_]T

const Table = struct {
const String = []const u8;
...

just cast to []const u8 and let the compiler generate the error

but if you did want to check, std.meta.Elem(field.field_type) == u8 gets you pretty close

just column[i].name = column_names[i];
