Struct Counter 

struct Counter {
    counts: Counts,
    test_file: bool,
    nested_test: bool,
    errors: Vec<String>,
}

Counts every #[expect] in a file: on items, and equally on statements, expressions, fields, variants and parameters, which syn’s visitor reaches through Visit::visit_attribute. An expectation inside a macro invocation’s tokens is not parsed and so not counted.

An expectation is production code unless its file is test code by test_files, or it sits on or inside an item marked #[cfg(test)].

Fields

counts: Counts

test_file: bool

nested_test: bool

errors: Vec<String>

Implementations

impl Counter

fn attr(&mut self, attr: &Attribute)

fn with_attrs(&mut self, attrs: &[Attribute], f: impl FnOnce(&mut Self))

Visits an item with nested_test set if the item is #[cfg(test)], so its own attributes and everything inside it are classified as tests.
