Implementations

impl Obj

pub fn fmt_with_precedence( &self, f: &mut Formatter<'_>, parent_precedent: u8, ) -> Result

按优先级输出：当子表达式优先级低于父节点时自动加括号，例如 ^ 下出现 + 则写成 (a + b)。

pub fn replace_bound_identifier(self, from: &str, to: &str) -> Obj

impl Obj

pub fn evaluate_to_normalized_decimal_number(&self) -> Option<Number>

pub fn two_objs_can_be_calculated_and_equal_by_calculation( &self, other: &Obj, ) -> bool

impl Obj

pub fn replace_with_numeric_result_if_can_be_calculated(&self) -> (Obj, bool)

Trait Implementations

impl Clone for Obj

fn clone(&self) -> Obj

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Display for Obj

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

Formats the value using the given formatter.

impl From<Atom> for Obj

fn from(atom: Atom) -> Self

Converts to this type from the input type.
