Struct hl7_parser::Segment

pub struct Segment {
    pub range: Range<usize>,
    pub fields: Vec<Field>,
}

Represents an HL7v2 segment

Fields

range: Range<usize>

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

fields: Vec<Field>

The fields found within the component

Implementations

impl Segment

pub fn field(&self, field: NonZeroUsize) -> Option<&Field>

Access a field via the 1-based HL7 field index

Returns

A reference to the field

pub fn field_mut(&mut self, field: NonZeroUsize) -> Option<&mut Field>

Mutably access a field via the 1-based HL7 field indexing

Returns

A mutable reference to the field

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

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

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");

assert_eq!(segment.source(message.source), "PID|1|12345|12345^^^MIE&1.2.840.114398.1.100&ISO^MR||MOUSE^MINNIE^S||19240101|F|||123 MOUSEHOLE LN^^FORT WAYNE^IN^46808|||||||||||||||||||");

pub fn field_at_cursor(&self, cursor: usize) -> Option<(NonZeroUsize, &Field)>

Locate a field at the cursor position

Arguments

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

Returns

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

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Segment

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Segment

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Segment> for Segments

fn from(value: Segment) -> Self

Converts to this type from the input type.

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

type Output = Field

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl PartialEq for Segment

fn eq(&self, other: &Segment) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Segment

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
