Struct ControlId

Source
pub struct ControlId;
Expand description

Adding “NODE_ID”, “BEGIN_ID”, and “END_ID” attribute to control statement

Implementations§

Source§

impl ControlId

Source

pub fn compute_unique_ids( con: &mut Control, cur_state: u64, two_if_ids: bool, ) -> u64

Adds the @NODE_ID attribute to all control stmts except emtpy ones. If two_if_ids is true, then if statements get a BEGIN_ID and END_ID instead of a NODE_ID

§Example:
seq { A; if cond {X} else{Y}; par { C; D; }; E }

gets the labels (if two_if_ids is):

@NODE_ID(0)seq {
  @NODE_ID(1) A;
  @BEGIN_ID(2) @END_ID(5) if cond {
    @NODE_ID(3) X
  }
  else{
    @NODE_ID(4) Y
  }
  @NODE_ID(6) par {
    @NODE_ID(7) C;
    @NODE_ID(8) D;
  }
  @NODE_ID(9) E;
}

if two_if_ids were false, the if statement would just get a single NODE_ID
