Describes errors in the initialization of flexi_logger.

Variants

OutputBadDirectory

Log file cannot be written because the specified path is not a directory.

OutputCleanupThread(Error)

Spawning the cleanup thread failed.

This error can safely be avoided with Logger::cleanup_in_background_thread(false).

OutputIo(Error)

Log cannot be written, e.g. because the configured output directory is not accessible.

SpecfileNotify(Error)

Filesystem notifications for the specfile could not be set up.

SpecfileToml(Error)

Parsing the configured logspec toml-file failed.

SpecfileIo(Error)

Specfile cannot be accessed or created.

SpecfileExtension(&'static str)

Specfile has an unsupported extension.

LevelFilter(String)

Invalid level filter.

Parse(String, LogSpecification)

Failed to parse log specification.

Log(SetLoggerError)

Logger initialization failed.

Poison

Some synchronization object is poisoned.

Trait Implementations

impl Debug for FlexiLoggerError

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

Formats the value using the given formatter.

impl Display for FlexiLoggerError

fn fmt(&self, __formatter: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Error for FlexiLoggerError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
