Struct LogConfig 

pub struct LogConfig {
    pub default_level: LogLevel,
    pub with_timestamps: bool,
    pub with_target: bool,
    pub with_file_line: bool,
    pub with_ansi: bool,
}

Configuration for logging initialization.

Why This Struct

Logging configuration often needs to vary between development and production:

• Development: verbose, colored output to terminal
• Production: JSON structured logs to file/stdout
• Testing: minimal output, captured by test harness

This struct captures these variations.

Fields

default_level: LogLevel

Default log level when RUST_LOG is not set.

with_timestamps: bool

Include timestamps in log output.

with_target: bool

Include target (module path) in log output.

with_file_line: bool

Include source file and line numbers.

with_ansi: bool

Use ANSI colors (disable for file output).

Implementations

impl LogConfig

pub fn new() -> Self

Create a new logging configuration with defaults.

pub fn with_level(self, level: LogLevel) -> Self

Set the default log level.

pub fn with_timestamps(self, enable: bool) -> Self

Enable or disable timestamps.

pub fn with_ansi(self, enable: bool) -> Self

Enable or disable ANSI colors.

pub fn development() -> Self

Configuration preset for development.

Verbose output with colors, file/line info for debugging.

pub fn production() -> Self

Configuration preset for production.

Clean output without colors (for structured log ingestion).

pub fn testing() -> Self

Configuration preset for testing.

Minimal output, captured by test harness.

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LogConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result
