Compiler cannot find `diesel::insert_into` for version from Rust package registry.

[anlaakso]

Versions

• Rust:1.22.0-nightly
• Diesel:0.16.0
• Database:Postgres
• Operating System: macOS Sierra

Feature Flags

• diesel:postgres
• diesel_codegen:postgres

Problem Description

I have experienced a very specific issue around 'diesel::insert_into' function.
If I run build with dependencies described below

[dependencies]
diesel = { version = "0.16.0", features = ["postgres"] }
diesel_codegen = { version = "0.16.0", features = ["postgres"] }
dotenv = "0.9.0"

the compiler says

error[E0425]: cannot find function `insert_into` in module `diesel`
  --> src/main.rs:31:31
   |
31 |     let rows: usize = diesel::insert_into(example)
   |                               ^^^^^^^^^^^ not found in `diesel`

But if I get diesel directly from GitHub, it works well.

[dependencies]
diesel = { git="https://github.com/diesel-rs/diesel.git", features = ["postgres"] }
diesel_codegen = { version = "0.16.0", features = ["postgres"] }
dotenv = "0.9.0"

insert_into is new and hasn't been published yet (see changelog). The documentation link in the readme tracks the master branch whereas the docs for the released version can be found on e.g. docs.rs.

Okay, thank you!

@Bobo1239 So I used the master branch in my Cargo.toml

[dependencies]
diesel = { git="https://github.com/diesel-rs/diesel.git", features = ["large-tables", "sqlite", "chrono"] }
diesel_codegen = { version="0.16.0", features = ["sqlite"] }

And when I compile with the feature large-tables. I get this errors:

@NotBad4U Hm, I'm getting the same error. Unfortunately I don't know what the problem is. Sorry.
