Crate ferogram_tl_parser 

Parser for Telegram’s Type Language (TL) schema files.

This crate is part of ferogram, an async Rust MTProto client built by Ankit Chaubey.

• Channel: t.me/Ferogram
• Chat: t.me/FerogramChat

Converts raw .tl schema text into a tl::Definition AST. That AST is then consumed by ferogram-tl-gen to produce the Rust type bindings in ferogram-tl-types.

Most users never touch this crate. It matters when you are upgrading the TL layer, writing a custom code generator, or doing schema introspection.

Usage

use ferogram_tl_parser::parse_tl_file;

let src = "user#12345678 id:long name:string = User;";
for def in parse_tl_file(src) {
    let def = def.unwrap();
    println!("{} #{:08x}", def.name, def.id);
}

parse_tl_file returns an iterator of Result<Definition, ParseError>. It handles both constructor and function sections of a .tl file.

AST

The main types are in the tl module:

• tl::Definition: one parsed TL declaration (constructor or function).
• tl::Parameter: a field name and type.
• tl::Type: a TL type reference (with optional generic argument).

Modules

errors

Parse error types for TL schema parsing.

tl

Core TL schema types: definitions, parameters, types, flags, and categories.

Functions

parse_tl_file

Parses a complete TL schema file, yielding Definitions one by one.
