gloo/value

Adapter-agnostic parameter value type.

Use these constructors in sql and query modules — they are encoded to DB-specific wire types by the adapter at execution time.

Types

GlooValue

</>

pub type GlooValue {
  GString(String)
  GInt(Int)
  GFloat(Float)
  GBool(Bool)
  GBitArray(BitArray)
  GTimestamp(timestamp.Timestamp)
  GNull
  GArray(List(GlooValue))
  GStringArray(List(String))
  GIntArray(List(Int))
}

Constructors

```
GString(String)
```
```
GInt(Int)
```
```
GFloat(Float)
```
```
GBool(Bool)
```
```
GBitArray(BitArray)
```
```
GTimestamp(timestamp.Timestamp)
```
```
GNull
```
```
GArray(List(GlooValue))
```
Postgres-only: used for UNNEST / array parameters. SQLite adapter will return DbError if this is encountered.
```
GStringArray(List(String))
```
Postgres text[] — use with = ANY($N) or UNNEST. SQLite adapter will return DbError; use manual IN (?,?,?) instead.
```
GIntArray(List(Int))
```
Postgres int8[] — use with = ANY($N) or UNNEST. SQLite adapter will return DbError; use manual IN (?,?,?) instead.
