Boost C++ Libraries

Gentle introduction to writing code with simple success-or-failure return types.

1. Inspecting result<T, EC>
2. TRY operations

Success-or-failure return types where failure can take two forms, expected/handled failure and unexpected/abort failure.

1. Inspecting outcome<T, EC, EP>

Describes the concept of NoValuePolicy and how to use no-value policies.

1. A custom no-value policy
2. Built-in policies

Success-or-failure return types where extra information in addition to the error code accompanies failure.

1. The Filesystem TS
2. Upgrading the Filesystem TS
3. Auto-throwing filesystem_error

How to metaprogram construction of objects which use result<T, EC> to return failure instead of throwing a C++ exception.

1. Two phase construction
2. A file handle
3. Phase 2 construction
4. Phase 3
5. construct<T>
6. Alternatives

Intercepting useful events such as initial construction, copies and moves so you can capture backtraces, fire debug breakpoints etc.

1. Keeping state
2. ADL bridging
3. Hook result
4. Custom exception ptr
5. Hook outcome

Interacting with result<T, EC> returning C++ functions from C code.

1. Limitations
2. Example C++ function
3. Calling it from C
4. Variations

Interoperating with std::expected<T, E> and other ValueOrError concept matching types.

1. Incommensurate E types
2. ValueOrError Concept
3. The HTTP library
4. The HTMLTidy library
5. The File I/O library
6. The Application
7. Mapping the HTTP library into the Application 1/2
8. Mapping the HTTP library into the Application 2/2
9. Mapping the File I/O library into the Application
10. Mapping the HTMLTidy library into the Application
