Fields

name: Option<String>

level: u8

parent: Option<usize>

children: Vec<usize>

offset: u32

size: u32

One occurrence.

occurs: u32

occurs_min: u32

The fewest occurrences: OCCURS DEPENDING ON’s minimum, else occurs.

table: bool

Declared with OCCURS, so references to it take a subscript.

depending_on: Option<Ref>

OCCURS … DEPENDING ON: the item holding the current number of occurrences.

odo: Vec<usize>

The OCCURS DEPENDING ON tables within this group, other than one within another of them: the occurrences past each one’s current count leave its length out.

moved_by: Vec<usize>

The OCCURS DEPENDING ON tables ahead of this item in its record: the occurrences past each one’s current count move it back (a variably located item, Language Reference SC27-8713-03, p. 206).

followed: bool

Whether an item after this one in its record moves with an OCCURS DEPENDING ON table in it.

index_names: Vec<String>

A table’s INDEXED BY names, and its ASCENDING/DESCENDING keys.

keys: Vec<(bool, Ref)>

local: bool

A LOCAL-STORAGE item: its offset is from the activation’s local storage.

kind: Kind

value: Option<Literal>

dims: Vec<(u32, u32)>

Stride and count of each OCCURS on the item and its ancestors, outermost first.

redefines: Option<String>

file: Option<u16>

The file whose record area holds the item, for a FILE SECTION record.

linkage: Option<u16>

The LINKAGE record the item belongs to, by its position among LINKAGE 01 and 77 items; its offset is from that record’s start, wherever the caller’s argument puts it.

object_class: Option<String>

The class-name of a typed object reference.

scaling: u32

PICTURE scaling positions P right of the digits: the item’s value is its digits times ten to this power.

alphabetic: bool

Of category alphabetic: a PICTURE of the symbol A alone.

pos: Pos

Implementations

impl Item

pub fn search_index(&self, varying: Option<&Ref>, pos: Pos) -> Option<Ref>

The index a SEARCH of this table steps: VARYING’s index-name when it is one of the table’s own, else the table’s first index-name, else VARYING’s item (Language Reference SC27-8713-03, p. 437).

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<(), Error>

Formats the value using the given formatter.
