Struct endbasic_core::exec::Machine

pub struct Machine { /* fields omitted */ }

Executes an EndBASIC program and tracks its state.

Implementations

impl Machine

pub fn clear(&mut self)

Resets the state of the machine by clearing all variable.

pub fn get_commands(&self) -> &HashMap<&'static str, Rc<dyn BuiltinCommand>>

Obtains immutable access to the builtin commands provided by this machine.

pub fn get_functions(&self) -> &HashMap<&'static str, Rc<dyn BuiltinFunction>>

Obtains immutable access to the builtin functions provided by this machine.

pub fn get_vars(&self) -> &Vars

Obtains immutable access to the state of the variables.

pub fn get_mut_vars(&mut self) -> &mut Vars

Obtains mutable access to the state of the variables.

pub fn get_var_as_bool(&self, name: &str) -> Result<bool>

Retrieves the variable name as a boolean. Fails if it is some other type or if it's not defined.

pub fn get_var_as_int(&self, name: &str) -> Result<i32>

Retrieves the variable name as an integer. Fails if it is some other type or if it's not defined.

pub fn get_var_as_string(&self, name: &str) -> Result<&str>

Retrieves the variable name as a string. Fails if it is some other type or if it's not defined.

pub async fn exec(&mut self, input: &mut dyn Read) -> Result<()>

Executes a program extracted from the input readable.

Note that this does not consume self. As a result, it is possible to execute multiple different programs on the same machine, all sharing state.

Trait Implementations

impl Default for Machine

pub fn default() -> Machine

Returns the "default value" for a type.
