Methods

impl Error

pub fn zero_map<T, F: FnOnce() -> T>(value: i32, result: F) -> Result<T>

If value is zero returns Ok(result()). Otherwise converts value to an Error and returns that.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

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

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<()> for Error

fn from(_: ()) -> Error

Performs the conversion.

impl From<Canceled> for Error

fn from(err: Canceled) -> Error

Performs the conversion.

impl From<EnumFromIntError> for Error

fn from(err: EnumFromIntError) -> Error

Performs the conversion.

impl From<NulError> for Error

fn from(err: NulError) -> Error

Performs the conversion.

impl PartialEq<Error> for Error

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl StructuralPartialEq for Error

impl TryFrom<i32> for Error

type Error = EnumFromIntError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.
