Enum IntegerValues 

pub enum IntegerValues<'a> {
    I32(DeviceArrayView<'a, i32>),
    I64(DeviceArrayView<'a, i64>),
}

Runtime-typed integer values from algorithm results.

This is used for integer-valued outputs that are not necessarily graph vertex IDs, such as component labels, core numbers, and triangle counts.

Variants

I32(DeviceArrayView<'a, i32>)

Values stored as 32-bit signed integers.

I64(DeviceArrayView<'a, i64>)

Values stored as 64-bit signed integers.

Implementations

impl IntegerValues<'_>

pub fn to_series(&self, runtime: &Runtime) -> Result<Series>

Copies this GPU array into an unnamed cudf Series bound to runtime.

Device-to-device copy: unavoidable because the cugraph C API owns result memory and frees it on drop. Matches Python cudf/cugraph behavior.

impl<'a> IntegerValues<'a>

pub fn len(&self) -> usize

Number of elements in the value array.

pub fn is_empty(&self) -> bool

Whether the value array is empty.

pub fn to_vec_i64(&self, handle: &EnteredContext<'_>) -> Result<Vec<i64>>

Copy to host as Vec<i64>, widening i32 values if needed.

pub fn to_vec_i32(&self, handle: &EnteredContext<'_>) -> Result<Vec<i32>>

Copy to host as Vec<i32>.

Returns an error if the underlying values are i64, since narrowing could lose data.

pub fn as_i32(&self) -> Option<&DeviceArrayView<'a, i32>>

Get the inner view as &DeviceArrayView<i32>, or None if i64.

pub fn as_i64(&self) -> Option<&DeviceArrayView<'a, i64>>

Get the inner view as &DeviceArrayView<i64>, or None if i32.

Trait Implementations

impl<'a> Debug for IntegerValues<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
