Struct SpgValue 

pub struct SpgValue { /* private fields */ }

Owned form of an SPG cell as it comes back from a query. Wraps spg_embedded::Value + the column’s static SpgTypeInfo so the decode path can drive sqlx’s type- compatibility check (Decode::compatible).

Implementations

impl SpgValue

pub fn new(inner: EngineValue, type_info: SpgTypeInfo) -> Self
