Add get-type command #730
Add get-type command #730
Conversation
The `get-type` command (requested in racer-rust#620) takes a line and character number which point to a complete identifier in the input text. The command will then attempt to determine the concrete type of that identifier.

hmm, can we not determine that it's an Option<usize>?

We don't put generic types into the matchstr property today; they're in the generic_types array instead. I could try and do something to push that data into matchstr but I'm not sure which approach would be better for tooling authors.

Shouldn't this be &str? name is a reference type (ie, a pointer).

Is there any reason this PR hasn't been merged? |

I don't specifically need this feature; I was hoping it would let me hack together completion for closures. I cloned the branch to test it, and trying to get the type of a closure argument causes a panic |

I would love to have this feature. I have to resort to hacks to get the type of a variable in neovim now. |

Hi @kngwyu, has there been any progress on this feature? I got super excited when I saw this PR, and then I realized how old it was. I would be happy to try to rebase/rewrite it on top of master, if nobody else is working on this and if this functionality is not supplied somewhere else (e.g. rustc). |

The
get-typecommand (requested in #620) takes a line and character number which point to a complete identifier in the input text. The command will then attempt to determine the concrete type of that identifier.Note that this also includes the travis updates from #728; this was necessary to make CI pass.
