Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IO(Error)

General I/O error occurred

LoggerError(FlexiLoggerError)

Available on crate features logger only.

Error while setting up or configuring logging

ModuleConfigFailed(Box<dyn Error>)

Module::config function returned an error

ModuleInitFailed(Box<dyn Error>)

Module::init function returned an error

ModuleListVoicesFailed(Box<dyn Error>)

Module::list_voices function returned an error

ModuleSetParamFailed(Box<dyn Error>)

Module::set_param function returned an error

ModuleSpeakFailed(Box<dyn Error>)

Module::speak or Module::speak_sync function returned an error

ModuleLoglevelSetFailed(Box<dyn Error>)

Available on non-crate feature logger only.

Module::loglevel_set function returned an error

ModuleDebugFailed(Box<dyn Error>)

Available on non-crate feature logger only.

Module::debug function returned an error

ProtoNoInit

Server did not send INIT message

ProtoParamMalformed(String, Option<ParseError>)

Error when parsing a malformed module property

Parameter will be None if a bad string on a string property was encountered, otherwise the numeric parsing error will be provided.

UnknownLoglevelParam(String)

An unknown name was supplied to loglevel_set

(The only protocol allowed param is “log_level”.)

UnknownParam(String)

An unknown name was supplied to set_param

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Self

Converts to this type from the input type.

impl From<FlexiLoggerError> for Error

fn from(source: FlexiLoggerError) -> Self

Converts to this type from the input type.
