Module ra_ap_base_db::fixture

Fixtures are strings containing rust source code with optional metadata. A fixture without metadata is parsed into a single source file. Use this to test functionality local to one file.

Simple Example:

r#"
fn main() {
    println!("Hello World")
}
"#

Metadata can be added to a fixture after a //- comment. The basic form is specifying filenames, which is also how to define multiple files in a single test fixture

Example using two files in the same crate:

"
//- /main.rs
mod foo;
fn main() {
    foo::bar();
}

//- /foo.rs
pub fn bar() {}
"

Example using two crates with one file each, with one crate depending on the other:

r#"
//- /main.rs crate:a deps:b
fn main() {
    b::foo();
}
//- /lib.rs crate:b
pub fn b() {
    println!("Hello World")
}
"#

Metadata allows specifying all settings and variables that are available in a real rust project:

• crate names via crate:cratename
• dependencies via deps:dep1,dep2
• configuration settings via cfg:dbg=false,opt_level=2
• environment variables via env:PATH=/bin,RUST_LOG=debug

Example using all available metadata:

"
//- /lib.rs crate:foo deps:bar,baz cfg:foo=a,bar=b env:OUTDIR=path/to,OTHER=foo
fn insert_source_code_here() {}
"
