Pattern Typestate

• Example Rust source code demonstrating the pattern "Typestate"

Usage

• cd pattern-typestate/

Fluent Constructor Examples

• Examples of using the typestate pattern to make a fluent constructor

• Techniques are gradually introduced from one example module to the next

• fluent_constructor_0

  • Demonstrates the basic typestate pattern as used with a fluent constructor

• fluent_constructor_1

  • Demonstrates specifying the state using a generic and phantom data

• fluent_constructor_2

  • Demonstrates a typestate fluent constructor for an external struct

• fluent_constructor_3

  • Demonstrates diverging and converging fluent constructor chain method paths

State Machine Examples

• Examples of using the typestate pattern to make a state machine

• state_machine_0

  • Demonstrates a typestate state machine that operates on data inside itself

• state_machine_1

  • Demonstrates a typestate state machine that operates on data outside itself
