Fields

items: Vec<Item>

conditions: Vec<Condition>

edits: Vec<Vec<Sym>>

The positions of each edited PICTURE.

currencies: Vec<String>

The currency sign value each edited PICTURE’s currency symbol stands for, empty without one.

file_areas: Vec<(u32, u32)>

Offset and size of each file’s record area, in declaration order.

record_lengths: Vec<Option<(u32, u32)>>

The least and greatest length of each file’s level-01 records, an OCCURS DEPENDING ON table counted at its fewest and at its most occurrences (Language Reference SC27-8713-03, p. 188); None for a file with none.

linkage_roots: Vec<usize>

The item of each LINKAGE record, in order.

local_size: u32

Bytes of LOCAL-STORAGE each activation gets.

size: u32

file_names: Vec<String>

Each FD and SD name, in declaration order: the highest qualifier of its records.

linage_counters: Vec<Option<usize>>

The LINAGE-COUNTER item of each file whose FD has LINAGE, which its file-name qualifies.

qualify: Qualify

The QUALIFY option Layout::resolve follows.

Implementations

impl Layout

pub fn name_files( &mut self, files: &[FileDecl], linage_counters: Vec<Option<usize>>, )

Names the files, so that a file-name qualifies its records and its LINAGE-COUNTER.

pub fn resolve( &self, name: &str, qualifiers: &[String], pos: Pos, ) -> Result<Resolved, Error>

A data item, condition-name or LINAGE-COUNTER named with its qualifiers, the last of which may be the file-name of an FD or SD (Language Reference SC27-8713-03, pp. 69-70). Under QUALIFY(EXTEND) a reference the standard’s rules find ambiguous names the one candidate it gives a complete set of qualifiers, if only one (Programming Guide SC27-8714-03, p. 400; Language Reference SC27-8713-03, pp. 67-68).
