Struct BceLossForward 

pub struct BceLossForward {
    pub name: &'static str,
    pub id: String,
    pub block_size: i32,
    pub kernel_source: String,
    pub entry_point_source: String,
    pub source: String,
}

Element-wise binary cross-entropy forward.

Assumes input is already a probability (sigmoid output), i.e. in (0, 1).

out = -(target * log(input) + (1 - target) * log(1 - input))

Grid: [ceil(n / BLOCK_SIZE), 1, 1], block [128, 1, 1].

Fields

name: &'static str

The kernel function’s name (e.g. "flash_attention2_forward").

id: String

Unique kernel identifier: fn_name + dtype(s) + const values joined by “__”.

block_size: i32

Compile-time kernel constant, from the annotated fn’s const generics.

kernel_source: String

The original kernel function source.

entry_point_source: String

The Rust source of the generated C-ABI entry-point wrapper function.

source: String

Combined source (kernel_source + "\n\n" + entry_point_source); used by the Kernel trait.

Implementations

impl BceLossForward

pub fn new(block_size: i32) -> Self

Constructs a new kernel instance for these compile-time parameters.

Trait Implementations

impl Kernel for BceLossForward

type Args<'__a> = (*mut f32, *mut f32, *mut f32, i32)

This kernel’s launch-argument tuple type.

fn id(&self) -> String

A content hash of this kernel’s source, used as a cache key.

fn name(&self) -> &str

This kernel’s name.

fn source(&self) -> &str

This kernel’s full source (DSL + kernel body + entry point wrapper).

fn kernel_source(&self) -> &str

This kernel’s body source, without the entry-point wrapper.

fn entry_point_source(&self) -> &str

Returns the Rust source of the generated C-ABI entry-point wrapper function.

fn entry_point_name(&self) -> String

Returns the PTX symbol name for this kernel: "{name}_entry_point".
