Enum DiscoveryError 

pub enum DiscoveryError {
    BaseDirNotFound,
    LogFileMissing {
        path: PathBuf,
    },
    UnsupportedPlatform,
}

Errors that can occur during log file discovery.

Variants

BaseDirNotFound

The platform-specific base directory could not be determined.

On Windows this means KnownFolder::LocalAppDataLow failed to resolve. On macOS this means the HOME environment variable is not set.

LogFileMissing

The resolved log file path does not exist on disk.

Callers should notify the user (e.g., “MTG Arena not found”) and poll periodically until the file appears.

Fields

path: PathBuf

The expected path that was checked.

UnsupportedPlatform

The current operating system is not supported.

Only Windows, macOS, and Linux (Steam/Proton via libraryfolders.vdf, Lutris fallback) are supported targets.

Trait Implementations

impl Clone for DiscoveryError

fn clone(&self) -> DiscoveryError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DiscoveryError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DiscoveryError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DiscoveryError

impl Error for DiscoveryError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for DiscoveryError

fn eq(&self, other: &DiscoveryError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
