Struct LocationQuery

pub struct LocationQuery {
    pub segment: String,
    pub segment_index: Option<usize>,
    pub field: Option<usize>,
    pub repeat: Option<usize>,
    pub component: Option<usize>,
    pub subcomponent: Option<usize>,
}

A location query that describes the location of a value within an HL7 message. The query is made up of the segment name, field index, repeat index, component index, and subcomponent index. Each part of the query is separated by a period (.), and each index is enclosed in square brackets ([]). For example, the query PID.5[1].1 would refer to the first subcomponent of the first component of the first repeat of the fifth field of the PID segment.

All indexes are 1-based.

Fields

segment: String

segment_index: Option<usize>

field: Option<usize>

repeat: Option<usize>

component: Option<usize>

subcomponent: Option<usize>

Implementations

impl LocationQuery

pub fn parse(query: &str) -> Result<Self, QueryParseError>

Parse a location query from a string. Equivalent to parse_location_query.

Trait Implementations

impl Clone for LocationQuery

fn clone(&self) -> LocationQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LocationQuery

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LocationQuery

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LocationQuery

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

Formats the value using the given formatter.

impl FromStr for LocationQuery

type Err = QueryParseError

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 LocationQuery

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 LocationQuery

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&String> for LocationQuery

type Error = QueryParseError

The type returned in the event of a conversion error.

fn try_from(value: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for LocationQuery

type Error = QueryParseError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for LocationQuery

type Error = QueryParseError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
