Struct Config 

pub struct Config {
    pub mappings: Vec<Mapping>,
    pub overrides: Vec<Override>,
}

Configuration for timetable formatting and room mappings.

Loaded from a TOML file containing room-to-department mappings and optional per-lesson overrides.

Fields

mappings: Vec<Mapping>

Room-to-department mapping rules

overrides: Vec<Override>

Per-week/day/period lesson overrides

Implementations

impl Config

pub fn load(path: &Path) -> Result<Self, ConfigError>

Load configuration from a TOML file.

Arguments

• path - Path to the config.toml file

Returns

A parsed Config structure.

Errors

Returns ConfigError if:

• The file cannot be read
• The TOML syntax is invalid
• Required fields are missing

Example

use timetable_core::config::Config;
use std::path::Path;

let config = Config::load(Path::new("config.toml"))?;
println!("Loaded {} room mappings", config.mappings.len());

pub fn get_style_for_room(&self, room_code: &str) -> Option<&Mapping>

Find the mapping for a given room code.

Returns the mapping with the longest matching prefix. If both ‘MA’ and ‘MA1’ are configured, room ‘MA10’ matches ‘MA1’ (3 chars) over ‘MA’ (2 chars), regardless of configuration order.

Arguments

• room_code - Room code to look up (e.g., “MA3”, “SC8”)

Returns

The matching Mapping, or None if no prefix matches.

Example

if let Some(mapping) = config.get_style_for_room("MA3") {
    println!("Room MA3 maps to: {}", mapping.map_id);
}

pub fn apply_overrides(&self, weeks: &mut [Week])

Apply configured overrides to parsed weeks.

Modifies lessons in-place based on override rules. Each override specifies a week, day, and period, and can update any combination of subject, room, teacher, or class code.

Arguments

• weeks - Mutable slice of week data to modify

Warnings

Prints warnings to stderr if:

• Week number is out of range
• Day or period name is invalid
• No matching lesson is found for an override

Example

let config = Config::load(Path::new("config.toml"))?;
let mut weeks = parse_pdf(Path::new("input/timetable.pdf"))?;

config.apply_overrides(&mut weeks);

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>
