Enum PadMode 

pub enum PadMode {
    Constant(f32),
    Reflect,
    Edge,
}

Padding mode for tensor pad operations.

Defines how values are filled when padding a tensor beyond its original boundaries.

Note: Currently, padding is only supported on the last two dimensions of a tensor (typically height and width for image data in NCHW format).

Modes

• Constant: Fill with a specified value (default: 0.0)
• Reflect: Mirror values at boundary, excluding edge (requires padding < dim_size)
• Edge: Replicate boundary values

Variants

Constant(f32)

Fill padded regions with a constant value.

Example

For tensor [1, 2, 3] with padding 2 on the left and value 0: Result: [0, 0, 1, 2, 3]

Reflect

Reflect values at the boundary, excluding the edge value.

Padding must be less than the dimension size (i.e., padding < dim_size).

Example

For tensor [1, 2, 3, 4] with padding 2 on the left: Result: [3, 2, 1, 2, 3, 4] (reflects from index 1, not 0)

Edge

Replicate the edge values.

Example

For tensor [1, 2, 3, 4] with padding 2 on the left: Result: [1, 1, 1, 2, 3, 4]

Trait Implementations

impl Clone for PadMode

fn clone(&self) -> PadMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PadMode

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

Formats the value using the given formatter.

impl Default for PadMode

fn default() -> PadMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for PadMode

fn deserialize<__D>( __deserializer: __D, ) -> Result<PadMode, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<E> From<E> for PadMode

where E: ElementConversion,

fn from(value: E) -> PadMode

Converts to this type from the input type.

impl PartialEq for PadMode

fn eq(&self, other: &PadMode) -> 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 PadMode

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for PadMode

impl StructuralPartialEq for PadMode
