Struct Merger

Source 
pub struct Merger<R, MF> { /* private fields */ }
Expand description

A struct you can use to merge entries from the sources by using the merge function provided to merge values when entries have the same key.

Implementations§

Source§

impl<R, MF> Merger<R, MF>

Source

pub fn builder(merge: MF) -> MergerBuilder<R, MF>

Creates a MergerBuilder from a merge function, it can be used to configure your Merger with the sources to merge.

Source§

impl<R: Read + Seek, MF> Merger<R, MF>

Source

pub fn into_stream_merger_iter(self) -> Result<MergerIter<R, MF>, Error>

Consumes this Merger and outputs a stream of the merged entries in key-order.

Source§

impl<R, MF> Merger<R, MF>
where R: Read + Seek, MF: MergeFunction,

Source

pub fn write_into_stream_writer<W: Write>( self, writer: &mut Writer<W>, ) -> Result<(), MF::Error>

Consumes this Merger and streams the entries to the Writer given in parameter.
