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(Vec<String>, LogSpecification)

Parsing a log specification failed.

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 1.41.0:

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
