}

Search modifiers that can be applied to search parameters.

See: https://build.fhir.org/search.html#modifiers

Variants

Exact

Exact string match (string parameters).

Contains

Contains substring (string parameters).

Text

Text search (token parameters).

Not

Negation - exclude matches.

Missing

Match if value is missing.

Above

Match codes above in hierarchy (token parameters).

Below

Match codes below in hierarchy (token parameters).

In

Match codes in a value set (token parameters).

NotIn

Match codes not in a value set (token parameters).

Identifier

Match on identifier (reference parameters).

Type(String)

Specify reference type (reference parameters).

OfType

Match on type (token parameters for polymorphic elements).

CodeOnly

Match on code only (token parameters).

Iterate

Iterate through results (_include modifier).

TextAdvanced

Advanced text search with synonyms and linguistic matching (FHIR v6.0.0).

This modifier enables sophisticated text matching that may include:

• Synonym expansion
• Linguistic stemming
• Fuzzy matching

Requires external terminology service integration.

CodeText

Match on code text/display value (token parameters, FHIR v6.0.0).

Searches the text/display value of a CodeableConcept or Coding rather than the code itself.

Implementations

impl SearchModifier

pub fn parse(s: &str) -> Option<Self>

Parses a modifier string, returning None for unknown modifiers.

pub fn is_valid_for(&self, param_type: SearchParamType) -> bool

Returns true if this modifier is valid for the given parameter type.

Trait Implementations

impl Clone for SearchModifier

fn clone(&self) -> SearchModifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SearchModifier

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SearchModifier

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SearchModifier

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

Formats the value using the given formatter.

impl Hash for SearchModifier

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 SearchModifier

fn eq(&self, other: &SearchModifier) -> 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 SearchModifier

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for SearchModifier

impl StructuralPartialEq for SearchModifier
