Struct BoolTensor 

pub struct BoolTensor { /* private fields */ }

CPU-resident tensor of booleans. Shape is metadata; storage is a flat Arc<Vec<bool>> for cheap clones.

Implementations

impl BoolTensor

pub fn from_vec( data: Vec<bool>, shape: Vec<usize>, ) -> Result<BoolTensor, FerrotorchError>

Build from a Vec + shape. Errors on numel mismatch.

pub fn from_slice( data: &[bool], shape: &[usize], ) -> Result<BoolTensor, FerrotorchError>

Build from a slice + shape (clones into a fresh Vec).

pub fn zeros(shape: &[usize]) -> BoolTensor

All-false tensor of the given shape.

pub fn ones(shape: &[usize]) -> BoolTensor

All-true tensor of the given shape.

pub fn from_predicate<T>( t: &Tensor<T>, pred: impl Fn(T) -> bool, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Build a mask by applying pred to every element of t. Useful for Tensor < 0, Tensor.is_finite(), etc.

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

Logical shape.

pub fn numel(&self) -> usize

Total number of elements.

pub fn ndim(&self) -> usize

Number of dimensions.

pub fn data(&self) -> &[bool]

Borrow the contiguous buffer.

pub fn not(&self) -> BoolTensor

Pointwise NOT.

pub fn and(&self, other: &BoolTensor) -> Result<BoolTensor, FerrotorchError>

Pointwise AND. Errors on shape mismatch.

pub fn or(&self, other: &BoolTensor) -> Result<BoolTensor, FerrotorchError>

Pointwise OR.

pub fn xor(&self, other: &BoolTensor) -> Result<BoolTensor, FerrotorchError>

Pointwise XOR.

pub fn reshape(&self, shape: &[usize]) -> Result<BoolTensor, FerrotorchError>

Reshape (must preserve numel; no data copy).

pub fn count_true(&self) -> usize

Number of true elements.

pub fn any(&self) -> bool

True if any element is true.

pub fn all(&self) -> bool

True if all elements are true.

pub fn gt<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise > comparing two float tensors of the same shape; produces a BoolTensor of matching shape. Mirrors torch.gt(a, b) returning a bool tensor. (#615)

pub fn lt<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise <. (#615)

pub fn ge<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise >=. (#615)

pub fn le<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise <=. (#615)

pub fn eq_t<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise ==. (#615)

pub fn ne<T>( a: &Tensor<T>, b: &Tensor<T>, ) -> Result<BoolTensor, FerrotorchError>

where T: Float,

Pointwise !=. (#615)

pub fn to_float<T>(&self) -> Result<Tensor<T>, FerrotorchError>

where T: Float,

Convert to a float tensor: true → 1.0, false → 0.0.
