Enum Error

pub enum Error {
    Io(Error),
    TerminfoParsing(Error),
    ParameterizedExpansion(Error),
    NotSupported,
    TermUnset,
    TerminfoEntryNotFound,
    CursorDestinationInvalid,
    ColorOutOfRange,
    // some variants omitted
}

An error arising from interacting with the terminal.

Variants

Io(Error)

Indicates an error from any underlying IO

TerminfoParsing(Error)

Indicates an error during terminfo parsing

ParameterizedExpansion(Error)

Indicates an error expanding a parameterized string from the terminfo database

NotSupported

Indicates that the terminal does not support the requested operation.

TermUnset

Indicates that the TERM environment variable was unset, and thus we were unable to detect which terminal we should be using.

TerminfoEntryNotFound

Indicates that we were unable to find a terminfo entry for the requested terminal.

CursorDestinationInvalid

Indicates that the cursor could not be moved to the requested position.

ColorOutOfRange

Indicates that the terminal does not support displaying the requested color.

This is like NotSupported, but more specific.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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

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<Error> for Error

fn from(err: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(val: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(val: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(val: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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