Crate spacetimedb

Provides safe abstractions around bindings-sys and re-exports #[spacetimedb] and #[duration].

Re-exports

• pub use log;
• pub use rand;
• pub use spacetimedb_bindings_sys as sys;
• pub use spacetimedb_lib;
• pub use spacetimedb_lib::sats;

Modules

• time_span

Macros

• dbg
  Functions like the standard library’s dbg! macro but prints as a DEBUG message to the console.
• duration
• query
  Implements query!(|row| …) macro for filtering rows.

Structs

• Address
  This is the address for a SpacetimeDB database or client connection.
• AnyReducer
  An erased reducer.
• Errno
  Error values used in the safe bindings API.
• Identity
• IndexDesc
  Describe a named index with an index type over a set of columns identified by their IDs.
• ReducerContext
  A context that any reducer is provided with.
• StdbRng
  A reference to the random number generator for this reducer call.
• TableId
• TableIter
  A table iterator which yields values of the TableType corresponding to the table.
• Timestamp
  A timestamp measured as micro seconds since the UNIX epoch.
• UniqueConstraintViolation
  A UNIQUE constraint violation on table type T was attempted.

Enums

• AlgebraicValue
  A value in SATS typed at some AlgebraicType.

Traits

• Deserialize
  A datastructure that can be deserialized from any data format supported by SATS.
• DeserializeOwned
  A data structure that can be deserialized in SATS without borrowing any data from the deserializer.
• FilterableValue
  A trait for types that can be serialized and tested for equality.
• Serialize
  A data structure that can be serialized into any data format supported by SATS.
• SpacetimeType
  A trait for types that can be represented as an AlgebraicType provided a typing context typespace.
• TableType
  A trait for the set of types serializable, deserializable, and convertible to AlgebraicType.

Functions

• decode_row
• decode_schema
• delete_by_col_eq
  Deletes all rows in the table identified by table_id where the column identified by col_id matches a value that can be serialized.
• delete_by_rel
  Deletes those rows, in the table identified by table_id, that match any row in relation.
• encode_row
• encode_schema
• get_table_id
  Queries and returns the table_id associated with the given (table) name.
• insert
  Insert a row of type T into the table identified by table_id.
• iter_by_col_eq
  Finds all rows in the table identified by table_id, where the row has a column, identified by col_id, with data matching val that can be serialized.
• random
  Generates a random value.
• rng
  Retrieve the random number generator for this reducer transaction, seeded by the timestamp of the reducer call.

Type Aliases

• Result

Attribute Macros

• spacetimedb
  Defines the #[spacetimedb(input)] procedural attribute.

Derive Macros

• Deserialize
• Serialize
• SpacetimeType
• TableType
  Generates code for treating this type as a table.
