Implementations

impl RequiresOneOf

pub fn len(&self) -> usize

Returns the number of alternatives.

pub fn is_empty(&self) -> bool

Returns whether there are any alternatives.

Trait Implementations

impl Clone for RequiresOneOf

fn clone(&self) -> RequiresOneOf

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequiresOneOf

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

Formats the value using the given formatter.

impl Default for RequiresOneOf

fn default() -> RequiresOneOf

Returns the “default value” for a type.

impl Display for RequiresOneOf

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

Formats the value using the given formatter.

impl PartialEq for RequiresOneOf

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