Enum SingleOrMultiValue

pub enum SingleOrMultiValue<'a> {
    Single(&'a ValType),
    Multi(&'a [ValType]),
}

A helper enum for representing either a single or multiple values.

Variants

Single(&'a ValType)

A single value.

Multi(&'a [ValType])

Multiple values.

Implementations

impl SingleOrMultiValue<'_>

pub fn is_empty(&self) -> bool

True if empty.

pub fn len(&self) -> usize

Count of values.

pub fn iter(&self) -> SingleOrMultiValueIterator<'_>

Iterate ofer the value types.

Trait Implementations

impl<'a> Clone for SingleOrMultiValue<'a>

fn clone(&self) -> SingleOrMultiValue<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl PartialEq<[ValType]> for SingleOrMultiValue<'_>

fn eq(&self, other: &[ValType]) -> 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<'a> PartialEq<SingleOrMultiValue<'a>> for &'a [ValType]

fn eq(&self, other: &SingleOrMultiValue<'a>) -> 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.
