Comprehensive error type for run operations.

This enum represents all possible errors that can occur during the development run process. Each variant provides context-specific information for debugging and error recovery.

Variants

ConfigNotFound(PathBuf)

Error when a configuration file is not found or cannot be read.

ConfigParse(String)

Error when parsing configuration fails.

ProfileNotFound(String, String)

Error when a profile is not found in the configuration.

EnvResolve(String)

Error when environment variable resolution fails.

EnvMissing(String)

Error when a required environment variable is missing.

Io(Error)

Error when file system operations fail.

Json(Error)

Error when JSON parsing fails.

ProcessStart(String)

Error when a process fails to start.

ProcessExit(i32)

Error when a process exits with a non-zero status.

ProcessSignal(String)

Error when a process is terminated by a signal.

PortBind(u16, String)

Error when port binding fails.

HotReload(String)

Error when hot-reload setup fails.

WatchMode(String)

Error when watch mode setup fails.

DependencyNotFound(String)

Error when a dependency is not found.

InvalidArgument(String)

Error when an invalid argument is provided.

InvalidConfig(String)

Error when run configuration is invalid.

ConflictingOptions(String)

Error when multiple conflicting options are provided.

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<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
