Struct GpuMainOverride 

pub struct GpuMainOverride { /* private fields */ }

A rank-local CUDA scope nested inside another engine’s PP stage scope.

CUDA contexts are a per-thread stack. The stream override alone is not enough: every rank-local allocation and launch must make that rank’s context current, then restore the caller’s context before the PP owner resumes issuing work.

Trait Implementations

impl Drop for GpuMainOverride

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
