Enum QuestionnaireItemOperator 

pub enum QuestionnaireItemOperator {
    NotEqual,
    Less,
    LessOrEqual,
    Equal,
    Greater,
    GreaterOrEqual,
    Exists,
}

QuestionnaireItemOperator. The criteria by which a question is enabled.

FHIR version: 5.0.0.

Variants

NotEqual

!=

Not Equals. True if no answer has a value that is equal to the enableWhen answer.

Less

<

Less Than. True if at least one answer has a value that is less than the enableWhen answer.

LessOrEqual

<=

Less or Equals. True if at least one answer has a value that is less or equal to the enableWhen answer.

Equal

=

Equals. True if at least one answer has a value that is equal to the enableWhen answer.

Greater

>

Greater Than. True if at least one answer has a value that is greater than the enableWhen answer.

GreaterOrEqual

>=

Greater or Equals. True if at least one answer has a value that is greater or equal to the enableWhen answer.

Exists

exists

Exists. True if the determination of ‘whether an answer exists for the question’ is equal to the enableWhen answer (which must be a boolean).

Trait Implementations

impl AsRef<str> for QuestionnaireItemOperator

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for QuestionnaireItemOperator

fn clone(&self) -> QuestionnaireItemOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuestionnaireItemOperator

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QuestionnaireItemOperator

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for QuestionnaireItemOperator

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

Formats the value using the given formatter.

impl From<QuestionnaireItemOperator> for CodeableConcept

fn from(code: QuestionnaireItemOperator) -> Self

Converts to this type from the input type.

impl From<QuestionnaireItemOperator> for Coding

fn from(code: QuestionnaireItemOperator) -> Self

Converts to this type from the input type.

impl FromStr for QuestionnaireItemOperator

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for QuestionnaireItemOperator

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 QuestionnaireItemOperator

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

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for QuestionnaireItemOperator
