Enum StringPadding 

pub enum StringPadding {
    Same,
    Valid,
}

The string-padding modes a Conv{1,2,3}d may be configured with, mirroring the padding: str branch of torch.nn.Conv{1,2,3}d (torch/nn/modules/conv.py:111-120, valid_padding_strings = {"same", "valid"}).

• StringPadding::Valid is equivalent to padding = 0 (no padding; aten/src/ATen/native/Convolution.cpp:1122-1124 padding == "valid" -> convolution_symint(.., {{0}}, ..)).
• StringPadding::Same pads so that, for stride = 1, the output spatial size equals the input spatial size. The total pad per dim is dilation * (kernel - 1), split ASYMMETRICALLY as left = total / 2, right = total - left (the END gets the extra pad when total is odd), mirroring _pooling_same_mode_padding_lr (aten/src/ATen/native/Pool.h:91-107) and the matching _ConvNd.__init__ _reversed_padding_repeated_twice arithmetic (conv.py:143-155). 'same' is rejected for strided convolutions (conv.py:117-120 / Convolution.cpp:1071).

Variants

Same

padding='same' — pad so output spatial size == input spatial size (stride must be 1). Asymmetric split per [same_pad_lr].

Valid

padding='valid' — no padding (equivalent to padding = 0).

Trait Implementations

impl Clone for StringPadding

fn clone(&self) -> StringPadding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StringPadding

impl Debug for StringPadding

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

Formats the value using the given formatter.

impl Eq for StringPadding

impl PartialEq for StringPadding

fn eq(&self, other: &StringPadding) -> 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.
