Rustとnicklelでのエラー PostgresQLなど

AdventCalendar2015 - nickel Webフレームワークを使ってみる - Qiita これ見た。

そして、まずこのだるい赤いエラー。

ググる。

qiita.com がヒット。

以下を実行

export OPENSSL_INCLUDE_DIR=/usr/local/opt/openssl/include
export DEP_OPENSSL_INCLUDE=/usr/local/opt/openssl/include

その後に再度cargo buildする。

次は・・。

   Compiling nickel_postgres v0.0.0 (https://github.com/nickel-org/nickel-postgres.git#22295ece)
/Users/shinriyo/.multirust/toolchains/stable/cargo/git/checkouts/nickel-postgres-f47cd59392fbdedc/master/src/middleware.rs:21:72: 21:80 error: mismatched types:
 expected `r2d2_postgres::SslMode`,
    found `postgres::SslMode<'_>`
(expected enum `r2d2_postgres::SslMode`,
    found enum `postgres::SslMode`) [E0308]

このファイルを弄る？ /Users/shinriyo/.multirust/toolchains/stable/cargo/git/checkouts/nickel-postgres-f47cd59392fbdedc/master/src/middleware.rs

r2d2_postgres::SslModeを想定してたのにpostgres::SslMode<'_>だ。

enumr2d2_postgres::SslModeを想定してたのにfound enum postgres::SslModeだ。

ってことか？ ん？
