tanzim-value

Package | Documentation | Repository

Foundational value types for the tanzim pipeline.

Types

[Value] — Bool, Int, Float, String, List, Map (no null)
[LocatedValue] — Value + [Location] (full originating [tanzim_source::Source], optional 1-based line/column)
[Map] — ordered Vec-backed map; last inserted key wins on lookup
[Error] — parse-time errors; use {error:#} for source snippet with caret underline

Location

[Location] holds the full originating [tanzim_source::Source] (name, options, resource, including any on_error policy) so any value or error can be traced back to how it was declared. Positions (line, column, length) are 1-based and stored as Option<NonZeroU32>. [Error] boxes its [Location] field so results stay small enough to return by value without tripping clippy::result_large_err. Construct via [Location::in_source] (real source) or [Location::at] (bare name/resource for synthetic origins); neither exposes NonZeroU32 to callers.

Example

use tanzim_value::{Value, LocatedValue, Location, Map};

let mut map = Map::new();
let location = Location::at("env", "", None, None, None);
map.insert(
    "port".to_string(),
    LocatedValue::new(Value::Int(8080), location.clone()),
);
map.insert(
    "host".to_string(),
    LocatedValue::new(Value::String("localhost".to_string()), location),
);
assert!(map.contains_key("port"));
assert_eq!(map.len(), 2);
