Trait SliceReduce 

Source 
pub trait SliceReduce: VTable {
    // Required method
    fn slice(
        array: &Self::Array,
        range: Range<usize>,
    ) -> VortexResult<Option<ArrayRef>>;
}

Required Methods§

Source

fn slice( array: &Self::Array, range: Range<usize>, ) -> VortexResult<Option<ArrayRef>>

Slice an array with the provided range without reading buffers.

This trait is for slice implementations that can operate purely on array metadata and structure without needing to read or execute on the underlying buffers. Implementations should return None if slicing requires buffer access.

§Preconditions

The range is guaranteed to be within bounds of the array (i.e., range.end <= array.len()).

Additionally, the range is guaranteed to be non-empty (i.e., range.start < range.end).

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
