Struct Resolver 

pub struct Resolver { /* private fields */ }

Effective settings of tag paths in one PLC, from the decorators, its [udt] and [tags] entries, its rules and groups, and the controller’s types (the /tags tags and types; UDT entries need them).

Implementations

impl Resolver

pub fn new( decorators: &Map<String, Json>, udt: &Map<String, Json>, tags: &Map<String, Json>, rules: Vec<Map<String, Json>>, groups: Vec<Map<String, Json>>, where_: &str, ) -> Result<Self, String>

A resolver without the controller’s types; an unknown decorator or a bad entry is an error naming its place.

pub fn from_body(body: &Json) -> Result<Self, String>

From a GET /tags body, as codegen sees it.

pub fn set_types(&mut self, tag_list: &[Json], types: &Map<String, Json>)

The controller structure (empty: unknown, so only [tags] entries and rules apply).

pub fn effective(&self, tag: &str) -> Settings

Settings of a tag path: rate_ms and together from the closest node that sets them, the other fields from the path itself (an element also from its array); then the rules, per field the first rule (file order) that sets it. A bit keeps no min, max, units, deadband, bits or together; writable falls back to its word’s.

pub fn group(&self, tag: &str, settings: &Settings) -> Option<Group>

The tag’s poll rate: from a decorator (named after it, "tag" when set inline), else the first matching poll group; None if neither sets one.

pub fn always(&self) -> Vec<String>

Tags read at tier 1 even with no subscribers: literal rule names and [tags] keys, and every instance of a UDT member whose entry says always (once the types are known).
