Enum DynArray

pub enum DynArray {
    F32(Array<f32>),
    F64(Array<f64>),
    I32(Array<i32>),
    I8(Array<i8>),
    U8(Array<u8>),
    Bool(Array<bool>),
}

Expand description

Array con tipo borrado (type-erased) que puede contener cualquier dtype

Similar a como NumPy maneja arrays internamente: el dtype se conoce en runtime.

§Ejemplo

let a = DynArray::F32(Array::new(vec![2], vec![1.0, 2.0]));
let b = DynArray::I32(Array::new(vec![2], vec![3, 4]));
 
// Operaciones devuelven DynArray con tipo promovido
let result = ops::add_dyn(&a, &b)?; // -> DynArray::F32
 
// Pattern matching para extraer el tipo concreto
match result {
    DynArray::F32(arr) => println!("f32: {:?}", arr.data),
    DynArray::I32(arr) => println!("i32: {:?}", arr.data),
    _ => {}
}

Variants§

F32(Array<f32>)

F64(Array<f64>)

I32(Array<i32>)

I8(Array<i8>)

U8(Array<u8>)

Bool(Array<bool>)

Implementations§

impl DynArray

pub fn dtype(&self) -> DType

Obtener el DType de este array

pub fn shape(&self) -> &[usize]

Obtener el shape de este array

pub fn len(&self) -> usize

Número de elementos

pub fn is_empty(&self) -> bool

Si el array está vacío

pub fn to_f32(&self) -> Array<f32>

Convertir a Array (con conversión si es necesario)

pub fn map_data<F, R>(&self, f: F) -> Result<R>
where F: FnOnce(&dyn Any) -> Result<R>,

Aplicar una función a los datos internos

pub fn into_typed<T: DTypeValue>(self) -> Result<Array<T>>

Extract the inner Array with zero-copy if types match, or cast if they don’t.

§Automatic Casting

If the internal dtype differs from T, this function will automatically cast/convert the data to T. This enables “automatic narrowing” (F64 -> F32) or normal promotion casting.

pub fn from_generic<T: DTypeValue>(arr: Array<T>) -> Self

Envolver un Array genérico en DynArray basándose en su dtype

Esto usa unsafe para transmute, pero es seguro porque verificamos el dtype
