Enum ExprError 

pub enum ExprError {
    UnexpectedEnd,
    UnexpectedToken(String),
    UnterminatedString,
    InvalidNumber(String),
}

Errors that can occur while parsing a WHERE expression.

Variants

UnexpectedEnd

The expression ended unexpectedly.

UnexpectedToken(String)

An unexpected token was encountered.

UnterminatedString

A string literal was not properly terminated.

InvalidNumber(String)

A numeric literal could not be parsed.

Trait Implementations

impl Debug for ExprError

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

Formats the value using the given formatter.

impl Display for ExprError

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

Formats the value using the given formatter.

impl Error for ExprError

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 PartialEq for ExprError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
