Struct Placement 

pub struct Placement {
    pub rank: u32,
    pub structure_type: Option<String>,
    pub mapped_type: Option<String>,
    pub standard_type: Option<StandardType>,
    pub path: Vec<StructureElement>,
    pub alt: Option<String>,
    pub lang: Option<String>,
    pub expansion: Option<String>,
    pub attributes: Vec<AttributeObject>,
}

Where one marked-content sequence sits in the tree: its rank in the tree’s depth-first order, and the structure type of the element holding it, as written, after the root’s /RoleMap, and as a standard type, with the standard-typed elements above it.

Covers ISO 32000-1 §14.7.3 and §14.8.4.

Fields

rank: u32

structure_type: Option<String>

The element’s /S, as the file writes it.

mapped_type: Option<String>

structure_type followed through the role map until a name the map has no entry for; the same name when the map never names it.

standard_type: Option<StandardType>

The standard type mapped_type names, None when it names none.

path: Vec<StructureElement>

The element and its ancestors that have a standard type, the root’s child first and the element itself last; an ancestor of no standard type is skipped, its children keeping their place.

alt: Option<String>

The alternate description (/Alt, §14.9.3) of the element, or of the nearest ancestor that has one, decoded as a text string.

lang: Option<String>

The language (/Lang, §14.9.2) of the element, or of the nearest ancestor that declares one; None leaves the document’s own.

expansion: Option<String>

The expansion (/E, §14.9.5) of the abbreviation or acronym the element’s text is, or the nearest ancestor’s, decoded as a text string.

attributes: Vec<AttributeObject>

Every attribute object of the element and its ancestors (§14.7.5), the root’s child’s first; for one element, the objects its /C classes name come before its direct /A objects, so a later object overrides an earlier one (see Placement::attribute).

Implementations

impl Placement

pub fn attribute( &self, element: ObjRef, owner: &str, key: &str, ) -> Option<&Object>

The value key takes for element among its attribute objects of owner: the last object that has the key wins, so a direct /A object overrides a class’s and a later class an earlier one, the order §14.8.5.3 gives the standard attributes. Inheritance from an ancestor is the caller’s, since only some attributes inherit.

Covers ISO 32000-1 §14.7.5, §14.7.5.2, §14.8.5 and §14.8.5.3.
