    Value(LiteralValue),
    Veto(Option<String>),
}

Veto(Option<String>)

Implementations

impl OperationResult

pub fn is_veto(&self) -> bool

pub fn value(&self) -> Option<&LiteralValue>

Trait Implementations

impl Clone for OperationResult

fn clone(&self) -> OperationResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperationResult

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

Formats the value using the given formatter.

impl PartialEq for OperationResult

fn eq(&self, other: &OperationResult) -> 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 Serialize for OperationResult

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
