`select()`

Function in Builtins

select: the free-function form of ReadonlyNode.select.

import { select } from 'typeshade'

The signature, the description and the examples come from the compiler's own source at commit 26de7be8.

Syntax

function select(cond: ReadonlyNode<'bool'>, ifTrue: number, ifFalse: number): Node<'f32'>;
function select<R extends string>(
  cond: ReadonlyNode<'bool'>,
  ifTrue: ReadonlyNode<R> | number,
  ifFalse: ReadonlyNode<R> | number,
): Node<R>;

Parameters

cond ReadonlyNode<'bool'>
ifTrue number
ifFalse number

Return value
