Struct Collection 

pub struct Collection { /* private fields */ }

Implementations

impl Collection

pub fn new(pool: Arc<HashMap<Arc<str>, Arc<Expression>>>) -> Self

pub fn to_value(&self) -> Arc<Value>

pub fn print(&self, writer: &mut Writer)

Trait Implementations

impl Clone for Collection

fn clone(&self) -> Collection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Collection

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

Formats the value using the given formatter.

impl Display for Collection

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

Formats the value using the given formatter.

impl ExpressionLike for Collection

fn to_formula(&self) -> String

Return the formula-string representation (round-trippable by the parser).

fn evaluate(&self, _context: &mut dyn ContextLike) -> Result<Arc<Value>>

Evaluate this expression with the provided ContextLike, returning a Value or error.

impl PartialEq for Collection

fn eq(&self, other: &Collection) -> 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 WriterLike for Collection

fn write(&self, writer: &mut Writer)

Serialize this expression with the given Writer.

fn to_stringized(&self) -> String

Return a string representation (raw unsafe output).

fn to_sanitized(&self) -> String

Return a sanitized string representation (escaped for safe output).

fn to_expressionized(&self) -> String

Return a sanitized string representation (escaped for safe output).
