Trait DupWriteCursor 

pub trait DupWriteCursor<'txn, T: DupTable>: WriteCursor<'txn, T> + DupReadCursor<'txn, T> {
    // Required methods
    fn append_dup(&mut self, key: &T::Key, value: &T::Value);
    fn remove_all_dup(&mut self);
}

Required Methods

fn append_dup(&mut self, key: &T::Key, value: &T::Value)

Appends a key/value pair to the end of the database. This operation fails if the key is less than the last key.

fn remove_all_dup(&mut self)

Removes all duplicate values for the current key.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
