The module includes functions for parsing raw frontmatter strings into structured data and converting structured data back into formatted strings. -use crate::types::Frontmatter; -use crate::{error::FrontmatterError, Format, Value}; +use serde::Serialize; use serde_json::Value as JsonValue; use serde_yml::Value as YmlValue; +use std::collections::HashMap; use toml::Value as TomlValue; +use crate::{ + error::FrontmatterError, types::Frontmatter, Format, Value, +}; + +// Constants for optimisation and validation +const SMALL_STRING_SIZE: usize = 24; +const MAX_NESTING_DEPTH: usize = 32; +const MAX_KEYS: usize = 1000; + +/// Options for controlling parsing behaviour +#[derive(Debug, Clone)] +pub struct ParseOptions { + /// Maximum allowed nesting depth + pub max_depth: usize, + /// Maximum allowed number of keys + pub max_keys: usize, + /// Whether to validate structure + pub validate: bool, +} + +impl Default for ParseOptions { + fn default() -> Self { + Self { + max_depth: MAX_NESTING_DEPTH, + max_keys: MAX_KEYS, + validate: true, + } + } +} + +/// Optimises string storage based on length +/// +/// For strings shorter than `SMALL_STRING_SIZE`, uses standard allocation. +/// For longer strings, pre-allocates exact capacity to avoid reallocations. +/// +/// # Arguments +/// +/// * `s` - The input string slice to optimise +/// +/// # Returns +/// +/// An optimised owned String +#[inline] +fn optimize_string(s: &str) -> String { + if s.len() <= SMALL_STRING_SIZE { + s.to_string() + } else { + let mut string = String::with_capacity(s.len()); + string.push_str(s); + string + } +} + /// Parses raw frontmatter string into a `Frontmatter` object based on the specified format. /// +/// This function attempts to parse the provided string into a structured `Frontmatter` +/// object according to the specified format.
