Crate mentat_core [−] [src]

Modules

counter
util

interpose	A helper macro to sequentially process an iterable sequence, evaluating a block between each pair of items.
interpose_iter	A helper to bind `name` to values in `across`, running `body` for each value, and running `inter` between each value. See `interpose` for examples.

DateTime	ISO 8601 combined date and time with time zone.
Keyword	A keyword is a symbol, optionally with a namespace, that prints with a leading colon. This concept is imported from Clojure, as it features in EDN and the query syntax that we use.
Schema	Represents a Mentat schema.
TxReport	A transaction report summarizes an applied transaction.
Utc	The UTC time zone. This is the most efficient time zone when you don't need the local time. It is also used as an offset (which is also a dummy type).
Uuid	A Universally Unique Identifier (UUID).

SQLValueType
SQLValueTypeSet	We have an enum of types, `ValueType`. It can be collected into a set, `ValueTypeSet`. Each type is associated with a type tag, which is how a type is represented in, e.g., SQL storage. Types can share type tags, because backing SQL storage is able to differentiate between some types (e.g., longs and doubles), and so distinct tags aren't necessary. That association is defined by `SQLValueType`. That trait similarly extends to `ValueTypeSet`, which maps a collection of types into a collection of tags.
Timelike	The common set of methods for time component.
ToMicros
UpdateableCache

AttributeMap	Map attribute entids to `Attribute` instances.
EntidMap	Map positive integer entids (`1`) to `Keyword` idents (`:db/ident`).
IdentMap	Map `Keyword` idents (`:db/ident`) to positive integer entids (`1`).
ValueRc	This type alias exists to allow us to use different boxing mechanisms for values. This type must implement `FromRc` and `Cloned`, and a `From` implementation must exist for `TypedValue`.
