Trait HostCas

pub trait HostCas: Sized + Send {
    // Required methods
    fn new(
        &mut self,
        bucket: Resource<Bucket>,
        key: String,
    ) -> impl Future<Output = Result<Resource<Cas>, Error>> + Send;
    fn current(
        &mut self,
        self_: Resource<Cas>,
    ) -> impl Future<Output = Result<Option<Vec<u8>>, Error>> + Send;
    fn drop(
        &mut self,
        rep: Resource<Cas>,
    ) -> impl Future<Output = Result<()>> + Send;
}

Required Methods

fn new( &mut self, bucket: Resource<Bucket>, key: String, ) -> impl Future<Output = Result<Resource<Cas>, Error>> + Send

Construct a new CAS operation. Implementors can map the underlying functionality (transactions, versions, etc) as desired.

fn current( &mut self, self_: Resource<Cas>, ) -> impl Future<Output = Result<Option<Vec<u8>>, Error>> + Send

Get the current value of the key (if it exists). This allows for avoiding reads if all that is needed to ensure the atomicity of the operation

fn drop( &mut self, rep: Resource<Cas>, ) -> impl Future<Output = Result<()>> + Send

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl<_T: HostCas + ?Sized + Send> HostCas for &mut _T

async fn new( &mut self, bucket: Resource<Bucket>, key: String, ) -> Result<Resource<Cas>, Error>

Construct a new CAS operation. Implementors can map the underlying functionality (transactions, versions, etc) as desired.

async fn current( &mut self, self_: Resource<Cas>, ) -> Result<Option<Vec<u8>>, Error>

Get the current value of the key (if it exists). This allows for avoiding reads if all that is needed to ensure the atomicity of the operation

async fn drop(&mut self, rep: Resource<Cas>) -> Result<()>
