Trait Filter 

pub trait Filter {
    // Required methods
    fn filter_existing_dirs(&self) -> ProjectDirs;
    fn filter_non_dirs(&self) -> ProjectDirs;
    fn filter_absent(&self) -> ProjectDirs;
    fn filter_denied(&self) -> ProjectDirs;
    fn filter_non_valid(&self) -> ProjectDirs;
}

Filter project directories

Required Methods

fn filter_existing_dirs(&self) -> ProjectDirs

Return only existing directories.

fn filter_non_dirs(&self) -> ProjectDirs

Return only non-directory entries in places where directories are expected. E.g. log file in the place of the log directory.

fn filter_absent(&self) -> ProjectDirs

Return only non-existing fs entries. E.g. missing log directory.

fn filter_denied(&self) -> ProjectDirs

Return only access denied fs entries. E.g. no read and execute access to log directory.

fn filter_non_valid(&self) -> ProjectDirs

Basically filter using !path.is_dir(), negation of the Filter::filter_existing_dirs

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
