Struct taos_query::RawError

pub struct RawError { /* private fields */ }

The Error type, a wrapper around raw libtaos.so client errors or dynamic error types that could be integrated into anyhow::Error.

Constructions

We prefer to use format_err to construct errors, but you can always use constructor API in your codes.

Constructor API

Use error code from native client. You can use it directly with error code

let error = Error::from_code(0x2603);

Or with error message from C API.

let error = Error::new(0x0216, r#"syntax error near "123);""#); // Syntax error in SQL

Implementations

impl Error

pub fn new_with_context( code: impl Into<Code>, err: impl Into<String>, context: impl Into<String> ) -> Error

pub fn new(code: impl Into<Code>, err: impl Into<String>) -> Error

pub fn context(self, context: impl Into<String>) -> Error

pub fn errno(&self) -> Code

👎Deprecated: Use self.code() instead

pub const fn code(&self) -> Code

pub fn message(&self) -> String

pub fn from_code(code: impl Into<Code>) -> Error

pub fn from_string(err: impl Into<Cow<'static, str>>) -> Error

pub fn from_any(err: impl Into<Error>) -> Error

pub fn any(err: impl Into<Error> + 'static) -> Error

pub fn success(&self) -> bool

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn provide<'_request>(&'_request self, request: &mut Request<'_request>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type based access to context intended for error reports.

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

impl Error for Error

fn custom<T>(msg: T) -> Error

where T: Display,

Raised when there is general error when deserializing a type.

fn invalid_type(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a type different from what it was expecting.

fn invalid_value(unexp: Unexpected<'_>, exp: &dyn Expected) -> Self

Raised when a Deserialize receives a value of the right type but that is wrong for some other reason.

fn invalid_length(len: usize, exp: &dyn Expected) -> Self

Raised when deserializing a sequence or map and the input data contains too many or too few elements.

fn unknown_variant(variant: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize enum type received a variant with an unrecognized name.

fn unknown_field(field: &str, expected: &'static [&'static str]) -> Self

Raised when a Deserialize struct type received a field with an unrecognized name.

fn missing_field(field: &'static str) -> Self

Raised when a Deserialize struct type expected to receive a required field with a particular name but that field was not present in the input.

fn duplicate_field(field: &'static str) -> Self

Raised when a Deserialize struct type received more than one of the same field.

impl FromStr for Error

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Error, <Error as FromStr>::Err>
