Struct Exp

pub struct Exp<'a> {
    pub ops: Vec<Op<'a>>,
}

Expression, internally it uses the Reverse Polish Notation (RPN) notation

Fields

ops: Vec<Op<'a>>

Implementations

impl<'a> Exp<'a>

pub fn from_str(exp: &'a str) -> Result<Self, Error>

pub fn is_empty(&self) -> bool

pub fn is_valid(&self) -> bool

pub fn eval(&self, ctx: &mut Ctx) -> bool

Trait Implementations

impl<'a> Debug for Exp<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Exp<'a>

fn default() -> Exp<'a>

Returns the “default value” for a type.

impl<'a> Display for Exp<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Exp<'a>

fn eq(&self, other: &Exp<'a>) -> 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.
