Enum Expression

pub enum Expression {
    Scalar(Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<&'ctx Value> + Send + Sync>),
    Sequence(Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<Box<dyn IEnumerable<'ctx, 'ctx> + 'ctx>> + Send + Sync>),

Trait Implementations

impl Clone for Expression

fn clone(&self) -> Expression

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expression

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

Formats the value using the given formatter.

impl From<Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<&'ctx Value, Error> + Send + Sync>> for Expression

fn from( expr: Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<&'ctx Value> + Send + Sync>, ) -> Self

Converts to this type from the input type.

impl From<Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<Box<dyn IEnumerable<'ctx, 'ctx, Item = Result<&'ctx Value, Error>> + 'ctx>, Error> + Send + Sync>> for Expression

fn from( expr: Arc<dyn for<'ctx> Fn(&ExecutionContext<'ctx>) -> Result<Box<dyn IEnumerable<'ctx, 'ctx> + 'ctx>> + Send + Sync>, ) -> Self
