Struct CompiledNestedSpec 

pub struct CompiledNestedSpec {
    pub spec: NestedRuleSpec,
    pub when: Option<WhenExpr>,
}

A NestedRuleSpec with its when: source pre-compiled into a crate::when::WhenExpr at rule-build time.

Mirrors the v0.9.5-era pattern for when_iter: on cross- file iteration rules: parse the source once at build, then evaluate per iteration with a fresh iter context. v0.9.12 closed the gap: pre-v0.9.12 the nested when: source string was re-parsed inside evaluate_for_each on every iteration (one parse per (entry, nested-rule) pair, sometimes thousands of redundant parses per cross-file rule eval). The Option<WhenExpr> on this struct is parsed exactly once.

Build sites (for_each_dir, for_each_file, every_matching_has in alint-rules) construct a Vec<CompiledNestedSpec> from Vec<NestedRuleSpec> in their build impl; evaluate_for_each consumes the compiled form.

Fields

spec: NestedRuleSpec

The original nested-rule spec — passed to NestedRuleSpec::instantiate per iteration to get a per-iteration full RuleSpec with template tokens substituted.

when: Option<WhenExpr>

Pre-compiled when: expression. None when the nested spec carried no when: clause.

Implementations

impl CompiledNestedSpec

pub fn compile( spec: NestedRuleSpec, parent_id: &str, idx: usize, ) -> Result<Self>

Compile a NestedRuleSpec — parsing its when: source string once. Surfaces a build-time config error ("<parent_id>: nested rule #<idx>: invalid when: ...") when the source fails to parse, so misconfigured nested-when clauses fail at config-load time instead of per-iteration during evaluation.

Trait Implementations

impl Debug for CompiledNestedSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
