something like this:
fn query(comptime T: type, allocator: Allocator, args: []const []const u8) !T {
const command = "query";
const stream = try sendAndGetStream(&[_][]const u8{ command, args });
#Can you concat a string literal and a [_][]const u8?

string literals can implicitly coerce to []const u8, yes
but thats not how to concatenate slices
since you don't know the length of args you'll have to use std.mem.concat
timber sandal
and allocate, right
gentle jasper
std.mem.concat allocates,yes
timber sandal
meh I might as well pass "query" in args
or append to a bounded array
which is becoming my fav collection
it would be awesome to have a bounded array that allocates if it exceeds the comptime size
like SmallVec in rust

Sounds like what you want is an ArrayList backed by a StackFallbackAllocator
StackFallbackAllocator allocates into a fixed buffer, and if you exceed the buffer size, then starts using a fallback allocator
You could use one something like this:
var sfb = std.heap.stackFallback(1024, allocator); // reserves a 1024 byte stack buffer
const sfba = sfb.get();
var bytes = std.ArrayList(u8).init(sfba);
defer bytes.deinit();
// do stuff with bytes
