Rustのエラーと闘っている。。。言語使用は流し見しかしてないから、具体的なエラー文を読んで、1個1個対処していく。
error[E0433]: failed to resolve: could not find `diesel` in the crate root
--> src/main.rs:13:11
|
13 | use self::diesel::prelude::*;
| ^^^^^^ could not find `diesel` in the crate root
error[E0599]: the method `filter` exists for struct `table`, but its trait bounds were not satisfied
--> src/main.rs:21:26
|
21 | let results = stocks.filter(code.eq(given_code as time_and_sales_deliver::schema::stocks::code))
| ^^^^^^ method cannot be called on `table` due to unsatisfied trait bounds
|
::: /app/src/schema.rs:1:1
|
1 | / table! {
2 | | stocks (code, datetime) {
3 | | code -> Int4,
4 | | datetime -> Timestamp,
... |
7 | | }
8 | | }
| |_- doesn't satisfy `table: Iterator`
|
= note: the following trait bounds were not satisfied:
`table: Iterator`
which is required by `&mut table: Iterator`
= help: items from traits can only be used if the trait is in scope
help: the following traits are implemented but not in scope; perhaps add a `use` for one of them:
|
3 | use std::iter::Iterator;
|
3 | use diesel::query_dsl::filter_dsl::FilterDsl;
|
3 | use diesel::query_dsl::QueryDsl;
|
3 | use futures::StreamExt;
|
and 1 other candidate
