Enum ExpressionParseError 

pub enum ExpressionParseError {
    InvalidSyntax {
        message: Arc<str>,
        input: Arc<str>,
        position: Option<usize>,
    },
}

Errors related to boolean expression parsing

These errors occur when parsing a boolean expression string fails.

Variants

InvalidSyntax

Failed to parse a boolean expression due to invalid syntax

Fields

message: Arc<str>

The error message from the parser

input: Arc<str>

The original input string that failed to parse

position: Option<usize>

Optional position in the input where the error occurred

Trait Implementations

impl Clone for ExpressionParseError

fn clone(&self) -> ExpressionParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionParseError

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

Formats the value using the given formatter.

impl Display for ExpressionParseError

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

Formats the value using the given formatter.

impl Error for ExpressionParseError

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<ExpressionParseError> for Error

fn from(err: ExpressionParseError) -> Self

Converts to this type from the input type.

impl From<ExpressionParseError> for ParseBoolExprError

fn from(err: ExpressionParseError) -> Self

Converts to this type from the input type.

impl PartialEq for ExpressionParseError

fn eq(&self, other: &ExpressionParseError) -> 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.
