Methods

impl Val

pub fn type_name(&self) -> String

Returns the Type of a Val as a string.

pub fn type_equal(&self, target: &Self) -> bool

Returns true if called with a Val of the same type as itself.

pub fn equal(     &self,     target: &Self,     file_name: &str,     pos: Position ) -> Result<bool, Error>

pub fn get_fields(&self) -> Option<&Vec<(Positioned<String>, Rc<Val>)>>

Returns the fields if this Val is a tuple. None otherwise.

Trait Implementations

impl PartialEq for Val

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl Debug for Val

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

Formats the value using the given formatter.

impl Clone for Val

fn clone(&self) -> Val

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Display for Val

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

Formats the value using the given formatter.

impl From<Val> for String

fn from(v: Val) -> String

Performs the conversion.

impl From<String> for Val

fn from(s: String) -> Val

Performs the conversion.
