Enum Decision

Source 
#[non_exhaustive]
pub enum Decision {
    Completed(usize),
    Wait(WaitArg),
    Blocking,
}
Expand description

Result of OpCode::pre_submit.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Completed(usize)

Instant operation, no need to submit

§

Wait(WaitArg)

Async operation, needs to submit

§

Blocking

Blocking operation, needs to be spawned in another thread
