1//! FIXME: write short doc here 1//! Fixtures are strings containing rust source code with optional metadata.
2//! A fixture without metadata is parsed into a single source file.
3//! Use this to test functionality local to one file.
4//!
5//! Example:
6//! ```
7//! r#"
8//! fn main() {
9//! println!("Hello World")
10//! }
11//! "#
12//! ```
13//!
14//! Metadata can be added to a fixture after a `//-` comment.
15//! The basic form is specifying filenames,
16//! which is also how to define multiple files in a single test fixture
17//!
18//! Example:
19//! ```
20//! "
21//! //- /main.rs
22//! mod foo;
23//! fn main() {
24//! foo::bar();
25//! }
26//!
27//! //- /foo.rs
28//! pub fn bar() {}
29//! "
30//! ```
31//!
32//! Metadata allows specifying all settings and variables
33//! that are available in a real rust project:
34//! - crate names via `crate:cratename`
35//! - dependencies via `deps:dep1,dep2`
36//! - configuration settings via `cfg:dbg=false,opt_level=2`
37//! - environment variables via `env:PATH=/bin,RUST_LOG=debug`
38//!
39//! Example:
40//! ```
41//! "
42//! //- /lib.rs crate:foo deps:bar,baz cfg:foo=a,bar=b env:OUTDIR=path/to,OTHER=foo
43//! fn insert_source_code_here() {}
44//! "
45//! ```
