Struct ExtensionValueWithArgs 

pub struct ExtensionValueWithArgs { /* private fields */ }

Object container for extension values, also stores the constructor-and-args that can reproduce the value (important for converting the value back to RestrictedExpr for instance)

Implementations

impl ExtensionValueWithArgs

pub fn new( value: Arc<dyn InternalExtensionValue + Send + Sync>, constructor: Name, args: Vec<RestrictedExpr>, ) -> Self

Create a new ExtensionValueWithArgs

pub fn value(&self) -> &dyn InternalExtensionValue

Get the internal value

pub fn typename(&self) -> Name

Get the typename of this extension value

pub fn constructor_and_args(&self) -> (&Name, &[RestrictedExpr])

Get the constructor and args that can reproduce this value

Trait Implementations

impl Clone for ExtensionValueWithArgs

fn clone(&self) -> ExtensionValueWithArgs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensionValueWithArgs

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

Formats the value using the given formatter.

impl Display for ExtensionValueWithArgs

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

Formats the value using the given formatter.

impl From<ExtensionValueWithArgs> for Expr

fn from(val: ExtensionValueWithArgs) -> Self

Converts to this type from the input type.

impl Ord for ExtensionValueWithArgs

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ExtensionValueWithArgs

fn eq(&self, other: &Self) -> 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 PartialOrd for ExtensionValueWithArgs

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticallyTyped for ExtensionValueWithArgs

fn type_of(&self) -> Type

Get the object’s type
