Implementations

impl JsProgram

pub fn validate(&self) -> Result<()>

验证程序的有效性

检查程序是否符合大小限制，并验证所有语句的有效性

Returns

• Ok(()) 如果程序有效
• Err(Error) 如果程序无效

pub fn optimize(&mut self)

优化程序

pub fn is_empty(&self) -> bool

检查程序是否为空

Trait Implementations

impl Clone for JsProgram

fn clone(&self) -> JsProgram

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsProgram

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

Formats the value using the given formatter.

impl Default for JsProgram

fn default() -> JsProgram

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for JsProgram

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for JsProgram

fn eq(&self, other: &JsProgram) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for JsProgram

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
