Errors that can occur during configuration operations

Variants

IoError(Error)

Encapsulates an underlying I/O error from the standard library.

This typically occurs when reading from or writing to configuration files.

TomlSerError(Error)

Represents errors that occur when serializing data to TOML format.

This typically happens when configuration data contains types that cannot be serialized to TOML.

TomlDeError(Error)

Represents errors that occur when deserializing data from TOML format.

This can happen when the TOML configuration content doesn’t match the expected structure.

MissingConfig(PathBuf)

Indicates that a required configuration file was not found.

The associated PathBuf indicates which file was missing.

InvalidValue(String)

Indicates that a configuration value is invalid or out of acceptable range.

This could include type mismatches, values out of range, or invalid formats.

MissingSection(String)

Indicates that a required section in a configuration file is missing.

Configuration files are often organized into sections, and this error indicates that a required section was not found.

SchemaError(String)

Indicates that the configuration doesn’t match the expected schema.

This could include missing fields, incorrect data types, or constraint violations.

DirectoryNotFound(PathBuf)

Indicates that a configuration directory was not found.

This typically occurs when trying to load multiple configuration files from a directory that doesn’t exist.

Trait Implementations

impl Debug for ConfigError

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

Formats the value using the given formatter.

impl Display for ConfigError

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

Formats the value using the given formatter.

impl Error for ConfigError

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.
