Mojo function

reduce_boolean

def reduce_boolean[reduce_fn: def[dtype: DType, width: SIMDLength](SIMD[dtype, width]) capturing thin -> Bool, continue_fn: def(Bool) capturing thin -> Bool, dtype: DType](src: Span[Scalar[dtype]], init: Bool) -> Bool

Computes a bool reduction of buffer elements. The reduction will early exit if the continue_fn returns False.

Parameters:

reduce_fn (def[dtype: DType, width: SIMDLength](SIMD[dtype, width]) capturing thin -> Bool): A boolean reduction function. This function is used to reduce a vector to a scalar. E.g. when we got 8xfloat32 vector and want to reduce it to a bool.
continue_fn (def(Bool) capturing thin -> Bool): A function to indicate whether we want to continue processing the rest of the iterations. This takes the result of the reduce_fn and returns True to continue processing and False to early exit.
dtype (DType): The dtype of the input.

Args:

src (Span[Scalar[dtype]]): The input buffer.
init (Bool): The initial value to use.

Returns:

Bool: The computed reduction value.
