Rule one is don't waste people's time. Waiting until the second paragraph to get to the point violates that rule. And that's assuming your reader knows what boost or std are.

[Blackthorn]

Virtually everyone who uses C++ knows what Boost and std are.

I would say most people who are writing C++ professionally should known what folly (and abseil from Google) is.

[downut]

Missing the most important part: avoid them (including boost), when you have a choice.

Professionals often don't have that choice. Cue many thousands of comments on HN why working in c++ sucks.

What should be used for a solid trie tree implementation?

Looking to implement a memory efficient search engine.

[exdsq]

Not being sarcastic here - can you roll your own?

[ravenstine]

Um... what? Why should I have any knowledge of some kitchen sink library at Facebook just because I write C++ elsewhere? (hypothetically speaking)

[Veuxdo]

Perfect. Put that in your title. Or at least in the first sentence of your description. Not paragraph 2.

[_ofdw]

I haven't touched C++ since first year university and even I know what boost and std are.
