Trait TxExt

pub trait TxExt {
    type Const;

    // Required method
    fn to_const(self) -> Self::Const;
}

Extension trait for Rc and Arc that allows up-casting a reference to ReadTransaction or WriteTransaction to ConstTransaction.

Required Associated Types

type Const

Required Methods

fn to_const(self) -> Self::Const

Returns self as a handle to a ConstTransaction rather than the subtype that was passed in.

This is still a shared handle to the same transaction.
