PR is available upstream: http-rs/route-recognizer#25

Temporary solution would be (http-rs/route-recognizer#25 (comment)):

[patch.crates-io.route-recognizer]
git = "https://github.com/miller-time/route-recognizer.rs"
rev = "d7bc06d2dc58a2c59d8f2cfbee2ab23b8188700d"

@dvic apparently crates.io won't accept a dependency via patch.

possibly related, I tried this in the iron router crate and travisCI couldn't find the dependency: iron/router#149

I'm not sure what the solution should be, sorry. 😞

[dvic]

That's weird.. Adding this to tide seems to solve the problem with route-recognizer:

[patch.crates-io]
route-recognizer = { git = "https://github.com/miller-time/route-recognizer.rs", rev = "d7bc06d2dc58a2c59d8f2cfbee2ab23b8188700d" }

The reason it doesn't work in iron/router#149 is probably related to something else? Rust version perhaps?

[miller-time]

@dvic I cloned tide and tried building with latest nightly. I don't get the warning that iron router gives me for some reason. But it can't seem to find the crate:

error[E0432]: unresolved import `route_recognizer`
 --> src/router/core.rs:7:5
  |
7 | use route_recognizer::{Match, Params, Router as MethodRouter};
  |     ^^^^^^^^^^^^^^^^ use of undeclared type or module `route_recognizer`

You're able to cargo +nightly build locally with that change?

EDIT - oops!

I was incorrectly removing dependencies.route-recognizer. This does build correctly if you don't make silly mistakes. 😀 I re-opened iron/router#149

[Nemo157]

route-recognizer 0.1.13 should fix this, it would be great if someone can submit a PR updating the minimum version that Tide requests.

[miller-time]

might be best done in #301 since I think that fixes a separate issue with nightly builds
