# Function serde::lib::core::path::absolute

pub fn absolute<P>(path: P) -> Result<PathBuf, Error> where    P: AsRef<Path>, 
🔬 This is a nightly-only experimental API. (absolute_path)
Expand description

Makes the path absolute without accessing the filesystem.

If the path is relative, the current directory is used as the base directory. All intermediate components will be resolved according to platforms-specific rules but unlike canonicalize this does not resolve symlinks and may succeed even if the path does not exist.

If the path is empty or getting the current directory fails then an error will be returned.

## Examples

### Posix paths

#![feature(absolute_path)]
fn main() -> std::io::Result<()> {
use std::path::{self, Path};

// Relative to absolute
let absolute = path::absolute("foo/./bar")?;
assert!(absolute.ends_with("foo/bar"));

// Absolute to absolute
let absolute = path::absolute("/foo//test/.././bar.rs")?;
assert_eq!(absolute, Path::new("/foo/test/../bar.rs"));
Ok(())
}

The path is resolved using POSIX semantics except that it stops short of resolving symlinks. This means it will keep .. components and trailing slashes.

### Windows paths

#![feature(absolute_path)]
fn main() -> std::io::Result<()> {
use std::path::{self, Path};

// Relative to absolute
let absolute = path::absolute("foo/./bar")?;
assert!(absolute.ends_with(r"foo\bar"));

// Absolute to absolute
let absolute = path::absolute(r"C:\foo//test\..\./bar.rs")?;

assert_eq!(absolute, Path::new(r"C:\foo\bar.rs"));
Ok(())
}

For verbatim paths this will simply return the path as given. For other paths this is currently equivalent to calling GetFullPathNameW This may change in the future.
