Function racer::complete_from_file

pub fn complete_from_file<'c, P, C>(
    filepath: P, 
    cursor: C, 
    session: &'c Session
) -> MatchIter<'c> where
    P: AsRef<Path>,
    C: Into<Location>, 

Search for completion at position in a file

• src - the file contents to search in
• filepath - path to file containing src
• pos - byte offset in file with path/expr to complete
• session - a racer::Session

Examples

extern crate racer;

let src = "
fn apple() {
}

fn main() {
    let b = ap
}";

println!("{:?}", src);

let cache = racer::FileCache::default();
let session = racer::Session::new(&cache);

session.cache_file_contents("lib.rs", src);

let got = racer::complete_from_file("lib.rs", racer::Location::Point(42), &session)
    .nth(0).unwrap();
assert_eq!("apple", got.matchstr);
assert_eq!(got.mtype, racer::MatchType::Function);
