Implementations

impl Expected

pub fn or(self, b: Self) -> Self

pub fn except(a: Self) -> Self

pub fn is_nil(&self) -> bool

pub fn first(a: Self, b: Self) -> Self

Trait Implementations

impl Clone for Expected

fn clone(&self) -> Expected

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expected

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

Formats the value using the given formatter.

impl Display for Expected

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

Formats the value using the given formatter.

impl Eq for Expected

impl Error for Expected

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 1.42.0:

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 Hash for Expected

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Expected> for Expected

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

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

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

This method tests for !=.
