enum File::Permissions

Overview

Represents a set of access permissions for a file. Not all permission sets will be supported on all platforms.

The binary representation of this enum is defined to be same representation as the permission bits of a unix st_mode field. File::Permissions can also be compared to its underlying bitset, for example File::Permissions::All == 0o777 will always be true.

On windows, only the OwnerWrite bit is effective. All file permissions will either be 0o444 for read-only files or 0o666 for read-write files. Directories are always mode 0o555 for read-only or 0o777.

Defined in:

file/info.cr
