Macros

debug

Logs a message at the debug level.

define_data_plugin

Defines a new type for storing data in Context.

define_derived_property

The “derived” variant of define_property! for defining simple derived property types. Defines a struct or enum with a standard set of derives and automatically invokes impl_derived_property! for it.

define_edge_type

define_entity

Defines a zero-sized struct with the right derived traits and implements the Entity trait. If you already have a type defined (struct, enum, etc.), you can use the impl_entity! macro instead.

define_global_property

Defines a global property with the following parameters:

define_multi_property

Defines a derived property consisting of a (named) tuple of other properties. The primary use case is for indexing and querying properties jointly.

define_property

Defines a struct or enum with a standard set of derives and automatically invokes impl_property! for it. This macro provides a concise shorthand for defining simple property types that follow the same derive and implementation pattern.

define_report

Use this macro to define a unique report type

define_rng

Use this to define a unique type which will be used as a key to retrieve an independent rng instance when calling Context::get_rng.

error

Logs a message at the error level.

impl_edge_type

impl_entity

Implements the Entity trait for the given existing type and defines a type alias of the form MyEntityId = EntityId<MyEntity>. For simple zero-sized types, use the define_entity! macro instead, which will define the struct and derive all the super traits.

impl_property

Implements the Property trait for the given property type and entity.

impl_property_eq

Implements PartialEq and Eq for a property type using Ixa’s generated byte-based equality behavior.

impl_property_eq_hash

Implements PartialEq, Eq, and Hash for a property type using Ixa’s generated byte-based equality and hashing behavior.

impl_property_hash

Implements Hash for a property type using Ixa’s generated byte-based hashing behavior.

info

Logs a message at the info level.

schedule_relative

Schedules an action after a delay relative to the context’s current time.

trace

Logs a message at the trace level.

track_periodic_value_change_counts

Tracks periodic value change counts with concise entity, property, and strata syntax.

warn

Logs a message at the warn level.

with

Creates an entity-scoped bundle of property values for queries and entity initialization.
