Enum SearchPathSettingsError 

pub enum SearchPathSettingsError {
    InvalidSearchPath(SearchPathError),
    FailedToReadVersionsFile {
        path: SystemPathBuf,
        error: Error,
    },
    VersionsParseError(TypeshedVersionsParseError),
}

Enumeration describing the various ways in which validation of the search paths options might fail.

If validation fails for a search path derived from the user settings, a message must be displayed to the user, as type checking cannot be done reliably in these circumstances.

Variants

InvalidSearchPath(SearchPathError)

FailedToReadVersionsFile

The typeshed path provided by the user is a directory, but stdlib/VERSIONS could not be read. (This is only relevant for stdlib search paths.)

Fields

path: SystemPathBuf

error: Error

VersionsParseError(TypeshedVersionsParseError)

The path provided by the user is a directory, and a stdlib/VERSIONS file exists, but it fails to parse. (This is only relevant for stdlib search paths.)

Trait Implementations

impl Debug for SearchPathSettingsError

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

Formats the value using the given formatter.

impl Display for SearchPathSettingsError

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

Formats the value using the given formatter.

impl Error for SearchPathSettingsError

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.
