Enum Pivoting 

pub enum Pivoting {
    Auto,
    None,
    GlobalCol,
    GlobalRow,
    Diagonal,
    LocalBlock,
}

Specifies the pivoting strategy (cuDSS only)

See: https://docs.nvidia.com/cuda/cudss/types.html#cudsspivottype-t

Variants

Auto

Automatic pivoting strategy (default)

Automatically selects the appropriate pivot type based on the reordering algorithm and matrix type:

1. For Ordering::Auto and Ordering::Amd:
   • Symmetric/Hermitian indefinite matrices: Uses Pivoting::Diagonal
   • General matrices: Uses Pivoting::LocalBlock
2. For Ordering::BtfColamd and Ordering::Colamd: Uses Pivoting::GlobalCol

CUDSS_PIVOT_AUTO

None

No pivoting

Used with Ordering::Auto and Ordering::Amd (MetisND and AMD).

CUDSS_PIVOT_NONE

GlobalCol

Global column pivoting

Used with Ordering::BtfColamd and Ordering::Colamd.

CUDSS_PIVOT_GLOBAL_COL

GlobalRow

Global row pivoting

Used with Ordering::BtfColamd and Ordering::Colamd.

CUDSS_PIVOT_GLOBAL_ROW

Diagonal

Diagonal pivoting

Used with Ordering::Auto and Ordering::Amd (MetisND and AMD).

For symmetric/Hermitian indefinite matrices, searches for pivot elements only within the diagonal of the supernode.

CUDSS_PIVOT_DIAGONAL

LocalBlock

Complete block pivoting

Use with Ordering::Auto and Ordering::Amd.

For general matrices, searches for pivot elements within the entire diagonal block of the supernode.

CUDSS_PIVOT_LOCAL_BLOCK

Implementations

impl Pivoting

pub fn from(pivoting: &str) -> Self

Returns the Pivoting by name (default is Auto)

Trait Implementations

impl Clone for Pivoting

fn clone(&self) -> Pivoting

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Pivoting

impl Debug for Pivoting

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Pivoting

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Pivoting

impl PartialEq for Pivoting

fn eq(&self, other: &Pivoting) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Pivoting

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
