Enum RepeatCount 

pub enum RepeatCount<'d> {
    Expr(Expression<'d>),
    Const(u64),
    Size(Expression<'d>),
    NestedSize {
        arr: Expression<'d>,
        path: Vec<NestStep<'d>>,
    },
    Inherited(Expression<'d>),
}

A counted loop’s iteration count: a repeat (N) loop’s count expression, a foreach loop’s static element count, or the number of elements a queue or dynamic array has when its foreach starts.

Variants

Expr(Expression<'d>)

Const(u64)

Size(Expression<'d>)

The size of this queue / dynamic array expression.

NestedSize

The size of the queue / dynamic array reached from arr by the enclosing foreach indices path (a[i][j] of foreach (a[i, j, k]) over int a[2][3][]), read when the loop is entered.

Fields

arr: Expression<'d>

path: Vec<NestStep<'d>>

Inherited(Expression<'d>)

A count the forking process already evaluated: the counter slot is copied in at the spawn (InheritedSlot::Counter), never initialized here. 0 is the count expression, which sizes the slot.

Implementations

impl<'d> RepeatCount<'d>

pub fn expr(&self) -> Option<Expression<'d>>

The expression the count is computed from, if the count is not a constant (for Size, the collection).

Trait Implementations

impl<'d> Clone for RepeatCount<'d>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'d> Debug for RepeatCount<'d>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
