Enum Item 

pub enum Item {
    Segment {
        name: String,
        required: bool,
        repeats: bool,
    },
    Group {
        name: String,
        required: bool,
        repeats: bool,
        items: Vec<Item>,
    },
}

One entry in an abstract message structure: a segment, or a named group of entries, each carrying whether the standard makes it required and whether it may repeat.

Variants

Segment

A segment, e.g. MSH.

Fields

name: String

The three-character segment name.

required: bool

Whether the structure requires it.

repeats: bool

Whether it may appear more than once here.

Group

A named group, e.g. ORDER_OBSERVATION.

Fields

name: String

The group name, as HL7’s structure tables spell it.

required: bool

Whether the structure requires it.

repeats: bool

Whether it may appear more than once here.

items: Vec<Item>

What the group contains, in order.

Implementations

impl Item

pub fn name(&self) -> &str

The segment or group name.

pub fn required(&self) -> bool

Whether the structure requires this item.

pub fn repeats(&self) -> bool

Whether this item may appear more than once in a row.

pub fn can_start(&self, segment: &str) -> bool

Can this item begin with a segment named segment?

For a group this walks its leading optional items plus the first required one — the group’s FIRST set — because an optional leading segment means a group can start at more than one segment name.

Trait Implementations

impl Clone for Item

fn clone(&self) -> Item

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Item

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

Formats the value using the given formatter.

impl Eq for Item

impl PartialEq for Item

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

Equality operator ==.

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

Inequality operator !=.
