MapWriter
A write-only version of the standard Map abstract data type.
Stack
An implementation of the stack abstract data type.

Real32
A 32-bit floating point number.
Real64
A 64-bit floating point number.

Represents a regular expression that can be used for matching and parsing strings.
SteppedRange
Similar to Range, but with a step value that indicates the number of steps to take during each iteration.
String
An immutable sequence of Unicode codepoints.
System
Provides utility methods that interface with the operating environment.
UInt
an unsigned 32 or 64 bit integer, as appropriate for the target architecture.

A 32-bit unsigned integer.
UInt64
A 64-bit unsigned integer.
UInt8
An 8-bit unsigned integer.

Holds a weak reference to an object.

Package frost.io

ByteOrder
Describes the byte order of multi-byte values when read from or written to a stream.
Console
Provides access to the standard input, output, and error streams.
File
Represents a file path, providing methods to query, read, and write files.
IndentedOutputStream
An output stream which indents the lines it writes.
InputStream
A stream of binary or character data which can be read from.
LineNumberInputStream
A InputStream which sits on top of another stream, tracking the current line and column as it reads from the underlying stream.
MemoryInputStream
An InputStream which reads from a String.
MemoryOutputStream
An OutputStream which stores the data written to it in a memory buffer.
OutputStream
A stream of binary or character data which can be written to.
PushbackInputStream
An input stream which allows data to be "pushed back" into it, so that it may be read again.

Package frost.math

Random
Provices methods for calculating pseudorandom numbers.
XorShift128Plus
A fast pseudorandom number generator using a XorShift+ algorithm with a period of 2^128 - 1.

Package frost.threads

Lock
A lock (mutex) which allows multiple threads to coordinate access to a shared resource.
MessageQueue
A queue which can be shared between multiple Threads, allowing any of them to submit messages to or pull messages out of it.
Notifier
A condition variable which helps multiple Threads coordinate their scheduling.
ScopedLock
An object which holds onto a Lock as long as the ScopedLock itself continues to exist.

Package frost.unsafe

Pointer
Represents a system-level pointer to a block of memory.
UnsafeMessageQueue
A message queue which allows mutable objects to be passed between threads, violating the normal Frost assumption that a mutable object is accessible only from a single thread.
