Struct OneShotCopier 

Source 
pub struct OneShotCopier { /* private fields */ }
Expand description

Implementations§

Source§

impl OneShotCopier

Source

pub fn new( fut: impl Future<Output = Result<Metadata>> + MaybeSend + 'static, ) -> Self

Create a new one-shot copier.

Source

pub fn completed() -> Self

Create a one-shot copier that has already completed.

Trait Implementations§

impl Send for OneShotCopier

§Safety

On wasm targets, futures are local but still only polled through &mut self.

Source§

impl Sync for OneShotCopier

§Safety

OneShotCopier is only accessed by &mut self.
