Struct mentat_core::StructuredMap

pub struct StructuredMap(pub IndexMap<ValueRc<Keyword>, Binding>);

A pull expression expands a binding into a structure. The returned structure associates attributes named in the input or retrieved from the store with values. This association is a StructuredMap.

Note that 'attributes' in Datomic's case can mean:

• Reversed attribute keywords (:artist/_country).
• An alias using :as (:artist/name :as "Band name").

We entirely support the former, and partially support the latter -- you can alias using a different keyword only.

Methods

Trait Implementations

impl From<StructuredMap> for Binding

fn from(value: StructuredMap) -> Self

Performs the conversion.

impl Clone for StructuredMap

fn clone(&self) -> StructuredMap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StructuredMap

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for StructuredMap

fn default() -> StructuredMap

Returns the "default value" for a type.

impl Eq for StructuredMap

impl PartialEq for StructuredMap

fn eq(&self, __arg_0: &StructuredMap) -> bool

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

fn ne(&self, __arg_0: &StructuredMap) -> bool

This method tests for !=.

impl From<IndexMap<ValueRc<Keyword>, Binding>> for StructuredMap

fn from(src: IndexMap<ValueRc<Keyword>, Binding>) -> Self
