/**
This class wraps a raw pointer that points to a Rust `EntityBuilder<InProgressBuilder>` object.
`EntityBuilder` provides a programmatic interface to performing assertions on a specific entity.
It provides functions for adding and retracting values for attributes for an entity within
an in progress transaction.
The `transact` function will transact the assertions that have been added to the `EntityBuilder`
and pass back the `TxReport` that was generated by this transact and the `InProgress` that was
used to perform the transact. This enables you to perform further transacts on the same `InProgress`
before committing.
```
let aEntid = txReport.entid(forTempId: "a")
let bEntid = txReport.entid(forTempId: "b")
do {
let builder = try mentat.entityBuilder(forEntid: bEntid)
try builder.add(keyword: ":foo/boolean", boolean: true)
try builder.add(keyword: ":foo/instant", date: newDate)
let (inProgress, report) = try builder.transact()
try inProgress.transact(transaction: "[[:db/add \(aEntid) :foo/long 22]]")
try inProgress.commit()
} catch {
...
}
```
The `commit` function will transact and commit the assertions that have been added to the `EntityBuilder`.
It will consume the `InProgress` used to perform the transact. It returns the `TxReport` generated by
the transact. After calling `commit`, a new transaction must be started by calling `Mentat.beginTransaction()`
in order to perform further actions.
```
let aEntid = txReport.entid(forTempId: "a")
do {
let builder = try mentat.entityBuilder(forEntid: aEntid)
try builder.add(keyword: ":foo/boolean", boolean: true)
try builder.add(keyword: ":foo/instant", date: newDate)
let report = try builder.commit()

/**
This class wraps a raw pointer that points to a Rust `InProgress` object.
`InProgress` allows for multiple transacts to be performed in a single transaction.
Each transact performed results in a `TxReport` that can be used to gather information
to be used in subsequent transacts.
Committing an `InProgress` commits all the transacts that have been performed using
that `InProgress`.
Rolling back and `InProgress` rolls back all the transacts that have been performed
using that `InProgress`.
```
do {
let inProgress = try mentat.beginTransaction()
let txReport = try inProgress.transact(transaction: "[[:db/add "a" :foo/long 22]]")
let aEntid = txReport.entid(forTempId: "a")
let report = try inProgress.transact(transaction: "[[:db/add "b" :foo/ref \(aEntid)] [:db/add "b" :foo/boolean true]]")
try inProgress.commit()
} catch {
...
}
```
`InProgress` also provides a number of functions to generating an builder to assert datoms programatically.
The two types of builder are `InProgressBuilder` and `EntityBuilder`.
`InProgressBuilder` takes the current `InProgress` and provides a programmatic interface to add
and retract values from entities for which there exists an `Entid`. The provided `InProgress`
is used to perform the transacts.
```
let aEntid = txReport.entid(forTempId: "a")
let bEntid = txReport.entid(forTempId: "b")
do {
let inProgress = try mentat.beginTransaction()
let builder = try inProgress.builder()
try builder.add(entid: bEntid, keyword: ":foo/boolean", boolean: true)
try builder.add(entid: aEntid, keyword: ":foo/instant", date: newDate)
let (inProgress, report) = try builder.transact()
try inProgress.transact(transaction: "[[:db/add \(aEntid) :foo/long 22]]")
try inProgress.commit()
} catch {
...
}
```
`EntityBuilder` takes the current `InProgress` and either an `Entid` or a `tempid` to provide
a programmatic interface to add and retract values from a specific entity. The provided `InProgress`
is used to perform the transacts.
```
do {
let transaction = try mentat.beginTransaction()
let builder = try transaction.builder(forTempId: "b")
try builder.add(keyword: ":foo/boolean", boolean: true)
try builder.add(keyword: ":foo/instant", date: newDate)

/**
This class wraps a raw pointer that points to a Rust `InProgressBuilder` object.
`InProgressBuilder` provides a programmatic interface to performing assertions for entities.
It provides functions for adding and retracting values for attributes for an entity within
an in progress transaction.
The `transact` function will transact the assertions that have been added to the `InProgressBuilder`
and pass back the `TxReport` that was generated by this transact and the `InProgress` that was
used to perform the transact. This enables you to perform further transacts on the same `InProgress`
before committing.
```
let aEntid = txReport.entid(forTempId: "a")
let bEntid = txReport.entid(forTempId: "b")
do {
let builder = try mentat.entityBuilder()
try builder.add(entid: bEntid, keyword: ":foo/boolean", boolean: true)
try builder.add(entid: aEntid, keyword: ":foo/instant", date: newDate)
let (inProgress, report) = try builder.transact()
try inProgress.transact(transaction: "[[:db/add \(aEntid) :foo/long 22]]")
try inProgress.commit()
...
} catch {
...
}
```
The `commit` function will transact and commit the assertions that have been added to the `EntityBuilder`.
It will consume the `InProgress` used to perform the transact. It returns the `TxReport` generated by
the transact. After calling `commit`, a new transaction must be started by calling `Mentat.beginTransaction()`
in order to perform further actions.
```
let aEntid = txReport.entid(forTempId: "a")
let bEntid = txReport.entid(forTempId: "b")
do {
let builder = try mentat.entityBuilder(forEntid: aEntid)
try builder.add(entid: bEntid, keyword: ":foo/boolean", boolean: true)
try builder.add(entid: aEntid, keyword: ":foo/instant", date: newDate)
let report = try builder.commit()
...
} catch {
