Enum NSTDResult 

#[repr(C, u8)]
pub enum NSTDResult<T, E> {
    Err(E),
    Ok(T),
}

Available on crate feature core only.

Defines a “result” type with success and error variants.

Variants

Err(E)

The error variant.

Ok(T)

The success variant.

Implementations

impl<T, E> NSTDResult<T, E>

pub fn unwrap(self) -> T

Attempts to return the contained Ok value in an NSTDResult.

This operation is only useful for testing code, it’s use in production should be discouraged.

Panics

Panics if self is an Err value.

pub fn expect(self, msg: &str) -> T

Attempts to return the contained Ok value in an NSTDResult.

Panics

Panics with msg if self is an Err value.

Trait Implementations

impl<T: Clone, E: Clone> Clone for NSTDResult<T, E>

fn clone(&self) -> NSTDResult<T, E>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug, E: Debug> Debug for NSTDResult<T, E>

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

Formats the value using the given formatter.

impl From<NSTDResult<usize, NSTDUnixIOError>> for NSTDIOResult

Available on crate feature io only.

fn from(value: NSTDUnixIOResult) -> Self

Converts an NSTDUnixIOResult into an NSTDIOResult.

impl<T: Ord, E: Ord> Ord for NSTDResult<T, E>

fn cmp(&self, other: &NSTDResult<T, E>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<T: PartialEq, E: PartialEq> PartialEq for NSTDResult<T, E>

fn eq(&self, other: &NSTDResult<T, E>) -> 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.

impl<T: PartialOrd, E: PartialOrd> PartialOrd for NSTDResult<T, E>

fn partial_cmp(&self, other: &NSTDResult<T, E>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
