Struct HeatingStatsDataTransfer

pub struct HeatingStatsDataTransfer;

Implements the HeatingStatsDataTransferTrait for transferring heating statistics to the SQL database.

This struct serves as the concrete component for persisting daily heating statistics into the configured SQL database.

Trait Implementations

impl HeatingStatsDataTransferTrait for HeatingStatsDataTransfer

fn transfer_heating_stats( &mut self, heating_stats_entry: HeatingStatsEntry, sql_interface_heating: &mut SqlInterfaceHeatingStats, ) -> Result<(), SqlInterfaceError>

Persists a daily heating statistics entry to the SQL database.

This implementation calls the underlying insert_heating_stats_entry method to write the provided data. The operation is typically an “upsert” (insert or update).

Arguments

• heating_stats_entry - The HeatingStatsEntry containing the complete statistics for a single day.
• sql_interface_heating - A mutable reference to the SqlInterfaceHeatingStats instance, used to perform the database write operation.

Returns

An empty Result (Ok(())) if the data was successfully inserted or updated in the database.

Errors

This function will return an Err variant of SqlInterfaceError if the underlying database operation fails. This is typically SqlInterfaceError::InsertHeatingStatsEntryFailure, which can be caused by:

• A lost or broken database connection.
• A violation of database constraints (e.g., a malformed date that violates the primary key).
• Insufficient permissions for the database user to perform INSERT or UPDATE operations.
• A malformed SQL query, which would indicate an internal logic error.
