Needed methods for the Token defined in cpclib_tokens

Required Methods

fn estimated_duration(&self) -> Result<usize, AssemblerError>

fn unroll(&self, env: &Env) -> Option<Result<Vec<&Self>, AssemblerError>>

Unroll the tokens when it represents a loop

fn disassemble_data(&self) -> Result<Listing, String>

Generate the listing of opcodes for directives that embed bytes

fn to_bytes_with_options( &self, option: EnvOptions ) -> Result<Vec<u8>, AssemblerError>

Provided Methods

fn number_of_bytes(&self) -> Result<usize, String>

fn number_of_bytes_with_context( &self, table: &mut SymbolsTableCaseDependent ) -> Result<usize, String>

Return the number of bytes of the token given the provided context

fn to_bytes(&self) -> Result<Vec<u8>, AssemblerError>

Dummy version that assemble without taking into account the context TODO find a way to not build a symbol table each time

fn to_bytes_with_context( &self, table: &mut SymbolsTableCaseDependent ) -> Result<Vec<u8>, AssemblerError>

Assemble the symbol taking into account some context, but never modify this context

fn is_valid(&self) -> bool

Check if the token is valid. We consider a token vlaid if it is possible to assemble it
