Detailed Description

Configuration for database connection.

Provides a structured way to pass connection parameters to backends, replacing raw connection strings with typed configuration.

Definition at line 50 of file database_backend.h.

Member Function Documentation

from_string()

connection_config database::core::connection_config::from_string ( const std::string & connect_string )

static

Construct connection_config from legacy connection string.

Parameters

connect_string

Connection string (format depends on backend)

Returns

Parsed connection configuration

Note: Parsing logic is backend-specific. This is a utility for backward compatibility.
