Struct ResultType

pub struct ResultType { /* private fields */ }

A type that denotes successful or unsuccessful operation.

Implementations

impl ResultType

pub fn new(ok: Option<ValueType>, err: Option<ValueType>) -> Self

Creates a new result type for the given Ok and Err variant types.

pub fn ok_ty(&self) -> Option<ValueType>

Gets the type of value returned for the Ok variant, if any.

pub fn err_ty(&self) -> Option<ValueType>

Gets the type of value returned for the Err variant, if any.

Trait Implementations

impl Clone for ResultType

fn clone(&self) -> ResultType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ResultType

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

Formats the value using the given formatter.

impl Hash for ResultType

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 PartialEq for ResultType

fn eq(&self, other: &ResultType) -> 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.
