Struct Error 

pub struct Error {
    pub code: SqlState,
    pub message: String,
    pub detail: Option<&'static str>,
    pub hint: Option<&'static str>,
    pub location: Option<usize>,
}

An error of the lexer or the parser.

Fields

code: SqlState

The SQLSTATE, for example 42601.

message: String

The primary message, as PostgreSQL writes it.

detail: Option<&'static str>

The detail, or None.

hint: Option<&'static str>

The hint, or None.

location: Option<usize>

The byte offset in the text that the error points to, or None.

Implementations

impl Error

pub fn position(&self, text: &str) -> Option<usize>

The position that an ErrorResponse gives: the number of the character that the location points to in text, where the first character is 1.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Error

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(error: Error) -> Self

The error of the engine with the SQLSTATE, the message, the detail and the hint. The location stays in the parser error: Error::position gives the position of the ErrorResponse.

impl PartialEq for Error

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
