pub struct Resrap { /* private fields */ }

Resrap is the main access point for single-threaded uses. It’s a collection of grammars which can be generated using parsing grammar.

Implementations

impl Resrap

pub fn new() -> Self

Creates and returns a new Resrap instance. The returned instance starts with no loaded grammars.

pub fn parse_grammar( &mut self, name: String, grammar: String, ) -> Result<(), String>

Parses a grammar string and stores it under the given name.

Arguments

• name - A unique identifier for this grammar (e.g., “C”), should be in ABNF format (Check osdc/resrap for more info on that).
• grammar - The grammar string to parse

Returns

Returns error generated while parsing

pub fn parse_grammar_file( &mut self, name: String, location: String, ) -> Result<(), String>

Parses a grammar from a file and stores it under the given name.

Arguments

• name - A unique identifier for this grammar (e.g., “C”), should be in ABNF format (Check osdc/resrap for more info on that).
• location - Path to the grammar file

Returns

Returns error generated while parsing

pub fn generate_with_seed( &self, name: &str, starting_node: String, seed: u64, tokens: usize, ) -> Result<Vec<String>, &str>

Generates content from the grammar identified by ‘name’ with a seed.

Arguments

• name - The grammar name to use
• starting_node - The starting symbol in the grammar for generation
• seed - A numeric seed to make generation deterministic
• tokens - Number of tokens to generate

Returns

A string containing the generated content.
