Function validate 

pub fn validate(
    schema: &Schema,
    document: &Document,
) -> Result<Vec<Diagnostic>, PrepareValidationError>

Prepares and validates one document.

Use PreparedValidator directly when validating multiple documents. Diagnostic order is deterministic but not a contract; see PreparedValidator::validate.

Example

use outlint_core::{load_schema, parse_markdown, validate, MarkdownOptions};

let loaded = load_schema("version: 1\ntitle: '*'\nsections: []\n")?;
let document = parse_markdown("# Guide\n", MarkdownOptions::default());
let diagnostics = validate(&loaded.schema, &document)
    .expect("loaded schema matchers compile");

assert!(diagnostics.is_empty());
