Struct ProgramBlock

pub struct ProgramBlock {
    pub context: Context,
}

is a part of the program, contains the context, i is capable of executing Use example:

use processor::program::{Program, ProgramBlock};
let mut program = Program::new();
let main = program.create_block();

// now use the main ProgramBlock

Fields

context: Context

Implementations

impl ProgramBlock

pub fn exec(&mut self, token: &str) -> Values

Executes a new token Use example:

use processor::program::{Program, ProgramBlock};

let mut program = Program::new();
let main = program.create_block();

main.borrow_mut().push_internal_key("echo", |tok, prog| {
    print!("{}" ,tok);
    processor::values::Values::Null
});
main.borrow_mut().exec("echo hello world!!");

pub fn push_internal_token(&mut self, token: Box<dyn Token>)

Push a new token in the context

pub fn push_internal_key( &mut self, key: &str, func: impl Fn(String, &mut ProgramBlock) -> Values + 'static, )

push a new key on the context

pub fn push_internal_memory(&mut self, key: &str, val: Values)

push a new value on the context

pub fn push_internal_function( &mut self, name: &str, func: impl Fn(String, &mut ProgramBlock) -> Values + 'static, )

push a new function on the context
