Enum LoggerError 

pub enum LoggerError {
    InvalidFormat(String),
    InvalidEnvFilter(String),
    TryInitError(String),
}

Errors that can occur when configuring and initialising the logger.

Variants

InvalidFormat(String)

The supplied format string is not a known LogFormat.

Returned by LogFormat::from_str, not by Logger::init — the builder itself is typed, so this cannot occur when values are passed as enums.

InvalidEnvFilter(String)

The env filter string could not be parsed by EnvFilter.

TryInitError(String)

A global tracing subscriber is already set (double-init).

Trait Implementations

impl Debug for LoggerError

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

Formats the value using the given formatter.

impl Display for LoggerError

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

Formats the value using the given formatter.

impl Eq for LoggerError

impl Error for LoggerError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for LoggerError

fn eq(&self, other: &LoggerError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
