Struct HeaderEvidence 

pub struct HeaderEvidence { /* private fields */ }

A tally of the files whose extension names their language outright, used to settle the bare .h headers whose extension does not.

The rule is the plain reading of a mixed tree: a project written mostly in C++ spells its headers .h because the extension is conventional, not because those headers are C. A project written mostly in C means C.

Only unambiguous extensions count, so the headers being settled never vote on their own language, and the verdict does not depend on how many of them there are.

Implementations

impl HeaderEvidence

pub const fn observe(&mut self, classification: Classification)

Count one classified file, ignoring the ones that prove nothing: Rust sources, and the .h headers awaiting this verdict.

pub const fn verdict(self) -> Option<Language>

The language to read bare .h headers as, when the tree says.

C++ only when the tree holds strictly more unambiguous C++ files than C ones. None when it holds neither, which is not a tie to be broken but a question this tally cannot answer: a header-only library has no files outside the headers, so there is nothing here to read the headers against.
