Provides the geny.Gen
data type, A Generator of elements of type A.
Generator is basically the inverse of a scala.Iterator
: instead of the core functionality being the pull-based hasNext
and next: T
methods, the core is based around the push-based generate
method. generate
is basically an extra-customizable version of foreach
, which allows the person calling it to provide basic control-flow instructions to the upstream Gens.
Unlike a scala.Iterator
, subclasses of Generator can guarantee any clean up logic is performed by placing it after the generate
call is made.
Transformations on a Generator are lazy: calling methods like filter
or map
do not evaluate the entire Gen, but instead construct a new Gen that delegates to the original. The only methods that evaluate the Generator are the "Action" methods like generate
/foreach
/find
, or the "Conversion" methods like toArray
or similar.
generate
takes a function returning Gen.Action
rather that Unit
. This allows a downstream Gen to provide basic control commands to the upstream Gens: i.e. Generator.End to cease enumeration of the upstream Gen. This allows it to avoid traversing and processing elements that the downstream Gen doesn't want/need to see anyway.

A Readable is a source of bytes that can be read from an InputStream
A Readable is a source of bytes that can be read from an InputStream
A subtype of Writable, every Readable can be trivially used as a Writable by transferring the bytes from the InputStream to the OutputStream, but not every Writable is a Readable.
Note that the InputStream is only available inside the readBytesThrough
, and may be closed and cleaned up (along with any associated resources) once the callback returns.

A Writable is a source of bytes that can be written to an OutputStream.
A Writable is a source of bytes that can be written to an OutputStream.
Essentially a push-based version of java.io.InputStream
, that allows an implementation to guarantee that cleanup logic runs after the bytes are written.
Writable is also much easier to implement than java.io.InputStream
: any code that previously wrote output to an ByteArrayOutputStream
or StringBuilder
can trivially satisfy the Writable interface. That makes Writable very convenient to use for allowing zero-friction zero-overhead streaming data exchange between different libraries.
Writable comes with implicit constructors from Array[Byte]
, String
and InputStream
, and is itself a tiny interface with minimal functionality. Libraries using Writable are expected to extend it to provide additional methods or additional implicit constructors that make sense in their context.
