Enum DisplayParsingError

#[non_exhaustive]
pub enum DisplayParsingError {
    DisplayNotSet,
    MalformedValue(Box<str>),
    NotUnicode,
    Unknown,
}

An error that occurred while parsing the $DISPLAY environment variable

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DisplayNotSet

No explicit display was provided and the $DISPLAY environment variable is not set.

MalformedValue(Box<str>)

The given value could not be parsed. The input to parsing is provided.

NotUnicode

The value of $DISPLAY is not valid unicode

Unknown

An unknown error occurred during display parsing.

This is XCB_CONN_CLOSED_PARSE_ERR.

Trait Implementations

impl Clone for DisplayParsingError

fn clone(&self) -> DisplayParsingError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayParsingError

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

Formats the value using the given formatter.

impl Display for DisplayParsingError

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

Formats the value using the given formatter.

impl Error for DisplayParsingError

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 From<DisplayParsingError> for ConnectError

fn from(err: DisplayParsingError) -> ConnectError

Converts to this type from the input type.

impl PartialEq for DisplayParsingError

fn eq(&self, other: &DisplayParsingError) -> 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.
