Function ethers_solc::utils::resolve_absolute_library

pub fn resolve_absolute_library(
    root: &Path,
    cwd: &Path,
    import: &Path
) -> Option<(PathBuf, PathBuf)>

Tries to find an absolute import like src/interfaces/IConfig.sol in cwd, moving up the path until the root is reached.

If an existing file under root is found, this returns the path up to the import path and the canonicalized import path itself:

For example for following layout:

<root>/mydependency/
├── src (`cwd`)
│   ├── interfaces
│   │   ├── IConfig.sol

and import as src/interfaces/IConfig.sol and cwd as src this will return (<root>/mydependency/, <root>/mydependency/src/interfaces/IConfig.sol)
