//! Module: validate
//!
//! Responsibility: top-level validation entrypoint over visitable trees.
//! Does not own: visitor diagnostics or per-type validation implementations.
//! Boundary: convenient crate-level validation surface that delegates to visitor traversal.

use crate::visitor::{
    ApplicationOperation, PathSegment, Visitable, VisitorAdapter, VisitorError, perform_visit,
    validate::ValidateVisitor,
};

///
/// validate
///
/// Validate a visitable tree, collecting issues by path.
///
/// Validation is non-failing at the traversal level. All validation
/// issues are collected and returned to the caller, which may choose
/// how to interpret them.
///
/// # Errors
///
/// Returns `VisitorError` when one or more validators report an issue.
///
pub fn validate(node: &dyn Visitable) -> Result<(), VisitorError> {
    let visitor = ValidateVisitor::new();
    let mut adapter = VisitorAdapter::new(visitor);

    perform_visit(&mut adapter, node, PathSegment::Empty);

    adapter
        .result()
        .map_err(|issues| VisitorError::new(ApplicationOperation::Validate, issues))
