This crate implements Diesel's procedural macros using the Macros 1.1 system. It depends on features introduced in Rust 1.15. Make sure to always use the latest stable release for optimal performance and feature support.
Diesel Codegen provides custom derive implementations for
Queryable
, Identifiable
,
Insertable
, AsChangeset
, and Associations
.
It also provides the macros infer_schema!
,
infer_table_from_schema!
, and
embed_migrations!
.
First, add this crate to Cargo.toml as so:
toml
diesel_codegen = { version = "0.16.0", features = ["postgres"] }
If you are using SQLite, be sure to specify sqlite
instead of postgres
in
the features
section.
Next, at the root of your crate add:
```rust
```
See the documentation for each trait/macro for additional details and configuration options.
