`lift()`

함수, IR 분류

Normalizes a NodeLike operand to a ReadonlyNode: a JS number becomes an f32 literal, and an existing node passes through unchanged.

import { lift } from 'typeshade'

구문

function lift(x: NodeLike): ReadonlyNode<string>

매개변수

x NodeLike

반환값

ReadonlyNode<string>

설명

Every free-function builtin (sin, min, construct, …) sends its operands through this, which is why sin(1) works without an explicit f32(1). Call it directly only when writing a new builtin wrapper that needs a plain node from a NodeLike argument. Method operands take a different path: a bare number passed to a method lifts to the receiver’s own scalar kind (u32, i32 or f64), so u32node.add(1) emits an unsigned literal.

예제

import { lift, f32 } from 'typeshade'

lift(2)       // Node<'f32'>: 2 lifted to an f32 literal
lift(f32(2))  // the same node, passed through unchanged
