/// Describes how a filesystem provider can satisfy a capability.

/// # Examples
///
/// ```rust
/// use qubit_fs::metadata::FileSystemCapabilitySupport;
///
/// assert!(matches!(FileSystemCapabilitySupport::Unsupported, FileSystemCapabilitySupport::Unsupported));
/// ```

    Conditional,
    /// The provider supports the capability for every valid request in its
    /// advertised filesystem scope.
