Struct TraditionalFor 

pub struct TraditionalFor<Init, Predicate, Update, Body> {
    pub init: Init,
    pub predicate: Predicate,
    pub update: Update,
    pub body: Body,
}

A traditional for loop in the style for (Init; Predicate; Update) { Body }. All the fields of this struct must be writable. For example:

use async_codegen::common::{SingularSeq, Str};
use async_codegen::context::EmptyContext;
use async_codegen::java::{AssignExpr, DeclareParam, FunctionCall, MemberAccess, Stmt, TraditionalFor};
use async_codegen::util::InMemoryOutput;
let for_loop = TraditionalFor {
  init: AssignExpr(DeclareParam(Str("int"), Str("i")), Str("0")),
  predicate: Str("i < 5"),
  update: Str("i++"),
  body: Stmt(MemberAccess(Str("System.out"), FunctionCall {
    name: Str("println"),
    args: SingularSeq(Str("i"))
  }))
};
let string = InMemoryOutput::print_output(EmptyContext, &for_loop);
assert_eq!("for (int i = 0; i < 5; i++) {\nSystem.out.println(i);\n}\n", string);

Fields

init: Init

The initial declaration of the loop variable

predicate: Predicate

The predicate that is checked before the next iteration

update: Update

The update that is applied after every iteration

body: Body

The body of the for loop

Trait Implementations

impl<Init: Clone, Predicate: Clone, Update: Clone, Body: Clone> Clone for TraditionalFor<Init, Predicate, Update, Body>

fn clone(&self) -> TraditionalFor<Init, Predicate, Update, Body>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Init: Debug, Predicate: Debug, Update: Debug, Body: Debug> Debug for TraditionalFor<Init, Predicate, Update, Body>

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

Formats the value using the given formatter.

impl<O, Init, Predicate, Update, Body> Writable<O> for TraditionalFor<Init, Predicate, Update, Body>

where O: Output, Init: Writable<O>, Predicate: Writable<O>, Update: Writable<O>, Body: Writable<O>,

async fn write_to(&self, output: &mut O) -> Result<(), O::Error>
