Struct FeatureDisabledError 

pub struct FeatureDisabledError { /* private fields */ }

An error indicating that a requested functionality is unavailable because its corresponding crate feature was not enabled at compile time.

This error typically occurs when a configuration file attempts to use a service (like a network logger) in a build that was optimized for local-use only.

How to resolve

If you encounter this error, ensure the required feature is enabled in your Cargo.toml:

[dependencies]
my_logger = { version = "Your version here", features = ["Feature name here"] }

Implementations

impl FeatureDisabledError

pub fn new(name: String) -> Self

Creates a new error instance for the specified feature name.

Example

let err = FeatureDisabledError::new("loki".to_string());

pub fn name(&self) -> &str

Returns the name of the feature that caused the error.

This can be used to programmatically decide whether to fallback to a different service.

Trait Implementations

Formats the value using the given formatter.

impl Display for FeatureDisabledError

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

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>)
