Zls error set inlay hint displays the full error set content

Help

Very new to zig. I’m getting these long inlay hints for an error set. In this case, shouldn’t it be displaying just std.posix.AcceptError ?

My code:

const std = @import("std");
const net = std.net;
const posix = std.posix;

pub fn main() void {
    const addr = try net.Address.parseIp("127.0.0.1", 8080);
    const listener = try posix.socket(addr.any.family, posix.SOCK_STREAM, posix.IPPROTO.TCP);
    defer posix.close(listener);

    try posix.setsockopt(listener, posix.SOL_SOCKET, posix.SO_REUSEADDR, &std.mem.toBytes(c_int, 1));
    try posix.bind(listener, addr.any);
    try posix.listen(listener, 128);

    while (true) {
        var client_addr: net.Address = undefined;
        var clien_adrr_len: posix.socklen_t = @sizeOf(net.Address);
        const socket = posix.accept(listener, &client_addr.any, &clien_adrr_len, 0) catch |err| {
            std.debug.print("Error accepting connection: {}\n", .{err});
            continue;
        };
        socket.close();
    }
}

i also experience this in emacs with eglot, where sometimes the length of the hint actually interrupts the scroll experience (which is probably more properly an emacs bug)… would be nice for me to be able to tweak or disable this behavior, but i don’t know how!

through your editor In-Editor Config - zigtools
global editor agnostic zls.json Config - zigtools
per project Per-Build Config - zigtools

Personally, I’d keep the inlays turned off by default. They’re pretty distracting and I haven’t seen other language modes in VSCode treat them as opt-out out instead of opt-in.

it tends to be enabled by default for newer languages
