Module render_common 

Shared pure-computation helpers used by both the synchronous crate::renderer and the asynchronous [crate::async_renderer] (when the async feature is enabled).

These functions have no &mut state dependencies and can be called from any context.

Enums

Iterable

Iteration abstraction for for loops.

Functions

add_like_js

Handles + operator: numeric add or string concat.

apply_builtin_filter_chain_on_cow_value

Applies a chain of builtin filters on a Cow value.

as_number

Numeric coercion: number, string parse, bool → 0/1.

builtin_filter_chain_application_order_valid

length may only appear as the final step.

can_dispatch_builtin_check

Checks if a name can be dispatched as a builtin function.

collect_attr_chain_from_getattr

If e is a chain of .attr segments on a plain variable (foo.bar.baz), returns the root name and path segments in order.

compare_values

Comparison operators.

eval_in

Implements membership test: array element, string substring, object key.

fill_loop_object

Fills a loop variable object for for loops.

inject_loop

Reuses the same loop object map in the innermost frame when possible.

is_test_parts

Right-hand side of is: identifier, string/null literal, or call (equalto(3)).

is_truthy

Nunjucks truthiness: null, false, 0/NaN, and "" are falsy.

iterable_empty

Checks if an iterable is empty.

iterable_from_value

Converts a Value to an Iterable.

jinja_slice_array

Jinja-compat slice (nunjucks sliceLookup).

json_num

Converts float to int if no fractional part.

json_partial_cmp

Partial ordering for numbers and strings.

peel_builtin_upper_lower_length_chain

Peels a chain of built-in upper / lower / capitalize / trim / length filters. Returns filter names in application order and the leaf expression.

try_dispatch_builtin

Dispatches builtin function calls (range, cycler, joiner).

Type Aliases

ExtendsLayout

{% extends %} parent expression plus block name → AST bodies.
