Trait Kernel 

pub trait Kernel: Sized + 'static {
    type Input<'a>;
    type Output;
}

Marker trait that binds typed Input and Output to a compute operation.

Implement this on a zero-sized marker struct, the struct itself carries no data; it just names the operation so Rust can resolve the right dispatch.

Required Associated Types

type Input<'a>

Input type for this kernel. The lifetime parameter allows borrowing host data (records, schema) without copying.

type Output

Output type produced after the kernel completes and results are downloaded back to host memory.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl Kernel for EmReduce

type Input<'a> = EmReduceInput<'a>

type Output = EmReduceOutput

impl Kernel for HelloBackend

type Input<'a> = HelloBackendInput

type Output = HelloBackendOutput
