3. PRINCIPIOS DE DESARROLLO
3.1 Optimización de Memoria
// ❌ MAL: Allocaciones innecesarias
fn process(allocator: Allocator, items: []const Item) ![]Result {
var results = try allocator.alloc(Result, items.len);
// ...
}
// ✅ BIEN: Reutilizar buffers, stack allocation cuando sea posible
fn process(items: []const Item, result_buf: []Result) []Result {
const count = @min(items.len, result_buf.len);
// ...
return result_buf[0..count];
}
Reglas:
- Preferir stack allocation sobre heap
- Usar
comptimepara cálculos en tiempo de compilación - Reutilizar buffers entre frames
- Evitar slices dinámicos cuando el tamaño es conocido
- Usar
@memsety@memcpypara operaciones bulk
3.2 Optimización de Rendimiento
// ❌ MAL: Múltiples pasadas
for (items) |item| {
if (item.visible) count += 1;
}
for (items) |item| {
if (item.visible) process(item);
}
// ✅ BIEN: Una sola pasada
for (items) |item| {
if (item.visible) {
count += 1;
process(item);
}
}
Reglas:
- Minimizar iteraciones (single-pass cuando posible)
- Early-exit en condiciones frecuentes
- Cache locality: acceso secuencial a memoria
- Evitar división (usar multiplicación por recíproco)
- Usar SIMD implícito via
@Vectorcuando aplique
3.3 Inmediato y Determinista
// ❌ MAL: Estado oculto, efectos secundarios
var global_counter: u32 = 0;
fn doSomething() void {
global_counter += 1;
}
// ✅ BIEN: Estado explícito, función pura
fn doSomething(state: *State) void {
state.counter += 1;
}
Reglas:
- Sin globals mutables (excepto ThemeManager/DataManager controlados)
- Funciones puras cuando posible
- Estado explícito pasado como parámetro
- Resultados predecibles dado el mismo input
3.4 API Consistente
Todos los widgets siguen el patrón:
// Variante simple (defaults)
pub fn widget(ctx: *Context, ...) Result { ... }
// Variante extendida (con config)
pub fn widgetEx(ctx: *Context, ..., config: Config) Result { ... }
// Variante con bounds explícitos
pub fn widgetRect(ctx: *Context, bounds: Rect, ..., config: Config) Result { ... }
