Enum NullAndStringOr

pub enum NullAndStringOr<'buffer, T> {
    Ok(T),
    Err(&'buffer str),
}

A successful method call result, or an error value decoded from an array of return values whose first entry is null and whose second entry is a string message.

This is a common convention used by various OpenComputers component APIs to report some (but not all) errors.

The 'buffer parameter is the lifetime of the buffer from which the error string is decoded. The T parameter is the type to decode if the call was successful.

Variants

Ok(T)

Err(&'buffer str)

Trait Implementations

impl<'buffer, T: Clone> Clone for NullAndStringOr<'buffer, T>

fn clone(&self) -> NullAndStringOr<'buffer, T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'buffer, T: Debug> Debug for NullAndStringOr<'buffer, T>

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

Formats the value using the given formatter.

impl<'buffer, Context, T: Decode<'buffer, Context>> Decode<'buffer, Context> for NullAndStringOr<'buffer, T>

fn decode( d: &mut Decoder<'buffer>, context: &mut Context, ) -> Result<Self, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl<'buffer, T: Hash> Hash for NullAndStringOr<'buffer, T>

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'buffer, T: Ord> Ord for NullAndStringOr<'buffer, T>

fn cmp(&self, other: &NullAndStringOr<'buffer, T>) -> 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<'buffer, T: PartialEq> PartialEq for NullAndStringOr<'buffer, T>

fn eq(&self, other: &NullAndStringOr<'buffer, T>) -> 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<'buffer, T: PartialOrd> PartialOrd for NullAndStringOr<'buffer, T>

fn partial_cmp(&self, other: &NullAndStringOr<'buffer, T>) -> 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.
