Struct LogConfig 

pub struct LogConfig {
    pub level: LogLevel,
    pub file_name: String,
    pub time_format: String,
    pub with_ansi: bool,
    pub with_target: bool,
    pub with_thread_names: bool,
    pub with_thread_ids: bool,
    pub with_line_number: bool,
    pub with_file: bool,
    pub with_level: bool,
}

Structure holding the logging configuration.

Every field is deserializable from a TOML file and has a sensible default so missing keys do not break loading (#[serde(default)]). Mirrors the boolean / time format options exposed by tracing_subscriber::fmt::Layer.

Fields

level: LogLevel

Logging level (off, error, warn, info, debug, trace)

file_name: String

Name of the log file (written in current directory)

time_format: String

Time format string (uses the time crate format_description syntax)

with_ansi: bool

Disable ANSI colors in the log file

with_target: bool

Include the module path (target) in each log line

with_thread_names: bool

Include thread names in each log line

with_thread_ids: bool

Include thread ids in each log line

with_line_number: bool

Include line numbers in each log line

with_file: bool

Include source file name in each log line

with_level: bool

Include the log level in each log line

Implementations

impl LogConfig

pub fn load_from_toml<P: AsRef<Path>>(path: P) -> Self

Load logging configuration from a TOML file. Returns the default configuration if the file cannot be opened or parsed. Only deserialization is supported (no serialization back to the file).

Trait Implementations

impl Clone for LogConfig

fn clone(&self) -> LogConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LogConfig

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

Formats the value using the given formatter.

impl Default for LogConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LogConfig

where LogConfig: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.
