Trait Implementations

impl Clone for ItemResult

fn clone(&self) -> ItemResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ItemResult

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

Formats the value using the given formatter.

impl Hash for ItemResult

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

where __H: Hasher,

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 PartialEq for ItemResult

fn eq(&self, other: &ItemResult) -> 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 TryFrom<i8> for ItemResult

type Error = UnknownItemResultType

The type returned in the event of a conversion error.

fn try_from(value: i8) -> Result<ItemResult, <ItemResult as TryFrom<i8>>::Error>

Performs the conversion.
