Review this generated settings patcher against the task.

Update a non-nil *Settings only through edit tags, reject unknown, nil, or incompatible values without panicking, never expose AdminToken, and reuse validated metadata in batch processing.

package config

import "reflect"

type Settings struct {
    Host       string `edit:"host"`
    Port       int    `edit:"port"`
    AdminToken string
}

func Apply(dst any, changes map[string]any) error {
    target := reflect.ValueOf(dst).Elem()
    for name, raw := range changes {
        field := target.FieldByName(name)
        if !field.IsValid() {
            continue
        }
        candidate := reflect.ValueOf(raw)
        if candidate.Type().ConvertibleTo(field.Type()) {
            field.Set(candidate.Convert(field.Type()))
        }
    }
    return nil
}
