Implementations

impl ConfigError

pub fn file_not_found(path: impl Into<String>) -> Self

Create a FileNotFound error.

pub fn parse_failed(context: impl Into<String>) -> Self

Create a ParseFailed error.

pub fn invalid_value(field: impl Into<String>, value: impl Into<String>) -> Self

Create an InvalidValue error.

pub fn missing_field(field: impl Into<String>) -> Self

Create a MissingField error.

pub fn io(context: impl Into<String>, source: Error) -> Self

Create an Io error.

pub const fn no_home_directory() -> Self

Create a NoHomeDirectory error.

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.

impl From<ConfigError> for TxGateError

fn from(source: ConfigError) -> Self

Converts to this type from the input type.
