Struct LoggingConfig 

pub struct LoggingConfig {
    pub log_dir: PathBuf,
    pub file_format: LogFormat,
    pub stderr_format: LogFormat,
    pub output: LogOutput,
}

Configuration for logging system initialization

This struct represents the domain-specific logging configuration that is independent of CLI parsing concerns. It can be constructed from CLI arguments or other configuration sources without creating circular dependencies.

Design Principles

• Independence: No dependency on presentation layer types
• Reusability: Can be constructed from various sources (CLI, config files, tests)
• Clarity: Clear field names and comprehensive documentation

Fields

log_dir: PathBuf

Directory where log files will be written

file_format: LogFormat

Format for file logging output

stderr_format: LogFormat

Format for stderr logging output

output: LogOutput

Output target (file-only vs file-and-stderr)

Implementations

impl LoggingConfig

pub fn new( log_dir: PathBuf, file_format: LogFormat, stderr_format: LogFormat, output: LogOutput, ) -> Self

Create a new logging configuration

Arguments

• log_dir - Directory for log files
• file_format - Format for file output
• stderr_format - Format for stderr output
• output - Output target configuration
