Struct NoGradGuard 

pub struct NoGradGuard { /* private fields */ }

RAII guard that disables gradient tracking for the duration of its lifetime, restoring the previous setting on drop.

Example

{
    let _guard = NoGradGuard::new();
    // ops here don't build the computation graph
}
// grad tracking is restored

Implementations

impl NoGradGuard

pub fn new() -> Self

Trait Implementations

impl Default for NoGradGuard

fn default() -> Self

Returns the “default value” for a type.

impl Drop for NoGradGuard

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.
