Struct PreparedArgs 

pub struct PreparedArgs { /* private fields */ }

A positional tuple of prepared call arguments.

Produced by EvalPolicy::prepare_call_args, it carries the values (eager, thunked, or quoted, per the policy and the per-position Demand) that a callable receives.

Examples

use sim_kernel::eval::PreparedArgs;

let args = PreparedArgs::new(Vec::new());
assert!(args.is_empty());
assert_eq!(args.len(), 0);
assert!(args.get(0).is_none());

Implementations

impl PreparedArgs

pub fn new(values: Vec<Value>) -> Self

Wraps an ordered list of prepared argument values.

pub fn values(&self) -> &[Value]

Returns the prepared values in positional order.

pub fn get(&self, index: usize) -> Option<&Value>

Returns the value at index, or None if out of range.

pub fn len(&self) -> usize

Returns the number of prepared arguments.

pub fn is_empty(&self) -> bool

Returns true when there are no prepared arguments.

pub fn as_expr_tuple(&self, cx: &mut Cx) -> Result<Expr>

Reconstructs the arguments as a single list Expr of their forms.

Trait Implementations

impl Clone for PreparedArgs

fn clone(&self) -> PreparedArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.
