Implementations

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) -> Result<bool, BuildError>

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

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

pub fn is_int(&self) -> bool

pub fn is_empty(&self) -> bool

pub fn is_float(&self) -> bool

pub fn is_string(&self) -> bool

pub fn is_tuple(&self) -> bool

pub fn is_env(&self) -> bool

pub fn is_list(&self) -> bool

pub fn is_bool(&self) -> bool

pub fn is_str(&self) -> bool

Trait Implementations

impl Clone for Val

fn clone(&self) -> Val

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Val

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

Formats the value using the given formatter.

impl Display for Val

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

Formats the value using the given formatter.

impl From<&Val> for Value

fn from(val: &Val) -> Self

Converts to this type from the input type.

impl From<&Value> for Val

fn from(val: &Value) -> Val

Converts to this type from the input type.

impl From<Rc<Value>> for Val

fn from(val: Rc<Value>) -> Val

Converts to this type from the input type.

impl From<String> for Val

fn from(s: String) -> Val

Converts to this type from the input type.

impl From<Val> for String

fn from(v: Val) -> String

Converts to this type from the input type.

impl From<Val> for Value

fn from(val: Val) -> Self

Converts to this type from the input type.

impl From<Value> for Val

fn from(val: Value) -> Val

Converts to this type from the input type.

impl PartialEq for Val

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