Struct Component

pub struct Component {
    pub range: Range<usize>,
    pub sub_components: Vec<SubComponent>,
}

Represents an HL7v2 sub-component

Fields

range: Range<usize>

The range (in char indices) in the original message where the component is located

sub_components: Vec<SubComponent>

The sub-components found within the component

Implementations

impl Component

pub fn sub_component( &self, sub_component: NonZeroUsize, ) -> Option<&SubComponent>

Access a sub-component via the 1-based HL7 sub-component index

Returns

A reference to the sub-component

pub fn sub_component_mut( &mut self, sub_component: NonZeroUsize, ) -> Option<&mut SubComponent>

Mutably access a sub-component via the 1-based HL7 sub-component index

Returns

A mutable reference to the sub-component

pub fn source<'s>(&self, message_source: &'s str) -> &'s str

Given the source for the original message, extract the (raw) string for this component

Arguments

• message_source - A string slice representing the original message source that was parsed

Examples

let message = include_str!("../test_assets/sample_oru_r01_generic.hl7");
let message = ParsedMessage::parse(&message, true).expect("can parse message");

let segment = message.segment("PID").expect("can get PID segment");
let field = segment.field(NonZeroUsize::new(3).unwrap()).expect("can get field 3");
let repeat = field.repeat(NonZeroUsize::new(1).unwrap()).expect("can get repeat 1");
let component = repeat.component(NonZeroUsize::new(4).unwrap()).expect("can get component 4");

assert_eq!(component.source(message.source), "MIE&1.2.840.114398.1.100&ISO");

pub fn sub_component_at_cursor( &self, cursor: usize, ) -> Option<(NonZeroUsize, &SubComponent)>

Locate a sub-component at the cursor position

Arguments

• cursor - The cursor location (0-based character index of the original message)

Returns

A tuple containing the HL7 sub-component index (1-based) and a reference to the sub-component. If the component doesn’t contain the cursor, returns None

Trait Implementations

impl Clone for Component

fn clone(&self) -> Component

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Component

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Component

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<I: Into<usize>> Index<I> for &Component

type Output = SubComponent

The returned type after indexing.

fn index(&self, index: I) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq for Component

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
