+
+Ječná Rozvrh API má svoji Rust knihovnu pro komunikaci s API. Obsahuje mappings pro Kotlin. Pro další jazyky budou mappingy v budoucnu.
+
+## Usage
+
+### `JecnaSuplClient` struct
+
+Knihovna používá `JecnaSuplClient` struct. Vytvoříte instanci pomocí `new`.
+
+```rust
+fn main() {
+    let client = JecnaSuplClient::new();
+}
+```
+
+### `set_provider(url: String)`
+
+Pokud nenastavíte vlastní provider path API použije hosted `https://jecnarozvrh.jzitnik.dev`
+
+Example usage:
+
+```rust
+client.set_provider("https://jecnarozvrh.example.com");
+```
+
+### `get_schedule(class_name: String) -> Result<SuplResult, SuplError>`
+
+Example usage:
+
+```rust
+let class = String::from("C2c");
+match client.get_schedule(class) {
+    Ok(result) => {
+        println!("Last update: {}", result.status.last_updated);
+    }
+    Err(error) => {
+        panic!("Error: {}", error)
+    }
+}
+```
+
+### `get_teacher_absence() -> Result<TeacherAbsenceResult, SuplError>`
+
+Example usage:
+
+```rust
+match client.get_teacher_absence() {
+    Ok(result) => {
+        /* Code */
+    }
+    Err(error) => {
+        panic!("Error: {}", error)
+    }
+}
+```
+
+### `get_all() -> Result<ApiResponse, SuplError>`
+
+Example usage:
+
+```rust
+match client.get_all() {
+    Ok(result) => {
+        /* Code */
+    }
+    Err(error) => {
+        panic!("Error: {}", error)
+    }
+}
+```
+
+### `report(content: String, class: String, report_location: ReportLocation) -> Result<(), SuplError>`
+
+Report function for reporting errors of the parser to the provider.
+
+Example usage:
+
+```rust
+let content = String::from("Detailni popis chyby");
+let class = String::from("C2c");
+let report_location = ReportLocation::Timetable;
+
+match client.report(content, class, report_location) {
+    Ok(result) => {
+        println!("Success");
+    }
+    Err(error) => {
+        panic!("Error: {}", error)
+    }
+}
+```
+
+## Datové struktury
+
+```rust
+#[derive(Debug, thiserror::Error, uniffi::Error)]
+pub enum SuplError {
+    #[error("Network error: {reason}")]
+    NetworkError { reason: String },
+    #[error("Parse error: {reason}")]
+    ParseError { reason: String },
+    #[error("Invalid date format: {reason}")]
+    DateFormatError { reason: String },
+    #[error("Internal runtime error: {reason}")]
+    RuntimeError { reason: String },
+}
+
+pub enum AbsenceEntry {
+    WholeDay {
+        teacher: Option<String>,
+        teacher_code: String,
+    },
+    Single {
+        teacher: Option<String>,
+        teacher_code: String,
+        hours: u16,
+    },
+    Range {
+        teacher: Option<String>,
+        teacher_code: String,

+    },
+    Exkurze {
+        teacher: Option<String>,
+        teacher_code: String,
+    },
+    Zastoupen {
+        teacher: Option<String>,
+        teacher_code: String,
+        zastupuje: SubstituteInfo,
+    },
+    Invalid { original: String },
+}
+
+pub struct AbsenceRange {
+    pub from: u16,
+    pub to: u16,
+}
+
+pub struct SubstituteInfo {
+    pub teacher: Option<String>,
+    pub teacher_code: String,
+}
+
+pub struct ChangeEntry {
+    pub text: String,
+    pub background_color: Option<String>,
+    pub foreground_color: Option<String>,
+    pub will_be_specified: Option<bool>,
+}
+
+pub struct ApiResponse {
+    pub status: Status,
+    pub schedule: HashMap<String, DailyData>,
+}
+
+pub struct DailyData {
+    pub info: DayInfo,
+    pub changes: HashMap<String, Vec<Option<ChangeEntry>>>,
+    pub absence: Vec<AbsenceEntry>,
+    pub takes_place: String,
+    pub reserved_rooms: Vec<Option<String>>,
+}
+
+pub struct DayInfo {
+    pub in_work: bool,
+}
+
+pub struct Status {
+    pub last_updated: String,
+    pub current_update_schedule: u16,
+}
+
+pub struct SuplResult {
+    pub status: Status,
+    pub schedule: HashMap<String, DailySchedule>,
+}
+
+pub struct DailySchedule {
+    pub info: DayInfo,
+    pub changes: Vec<Option<ChangeEntry>>,
+    pub absence: Vec<AbsenceEntry>,
+    pub takes_place: String,
+}
+
+pub struct TeacherAbsenceResult {
+    pub absences: HashMap<String, Vec<AbsenceEntry>>,
+}
+```
+
+## Mappings do jiných jazyků
+
+### Kotlin
+
+- [Mappings (required)](https://mvnrepository.com/artifact/cz.jzitnik/jecna-supl-client)
+
+Jednotlivé buildy:
+
+- [Android](https://mvnrepository.com/artifact/cz.jzitnik/jecna-supl-client-android)
+- [Linux X64](https://mvnrepository.com/artifact/cz.jzitnik/jecna-supl-client-linux-x64)
+- [Windows X64](https://mvnrepository.com/artifact/cz.jzitnik/jecna-supl-client-windows-x64)
+
+Všechny funkce jsou mappovány do `camelCase`. **Nejedná se o suspend funkce!**
