Struct thingvellir::Commit

pub struct Commit<Data>(_, _);

Specifies how the execute_mut should be committed to the upstream.

This allows you to control the durability of your data mutation.

Implementations

impl<Data> Commit<Data>

pub fn immediately(data: Data) -> Self

Persist the item immediately. The execution future will not resolve until your write has been been acknowledged by the upstream layer.

pub fn default(data: Data) -> Self

Persist the data, using the default persistence policy for the service.

pub fn within(data: Data, duration: Duration) -> Self

Ensure that the data is persisted within a given duration.

pub unsafe fn noop(data: Data) -> Self

The mutation resulted in a no-op. Do not try to persist the data in any way.

Safety

This function is unsafe, as it’s up to you to make sure to only call this if and only if the data truly did not change. Since you’re getting a &mut to the data, this contract cannot be statically enforced. So, it’s up to you to use correctly.
