Enum ExpansionError 

pub enum ExpansionError {
    NumConversionFailed(String),
}

An error type representing the failure to expand a parsed node.

This enum is used to indicate errors that can occur during the expansion of a parsed node. It provides detailed information about the specific type of error encountered.

Variants

• NumConversionFailed(String): An error indicating that a number conversion failed during expansion. It contains a string representing the value that failed to be converted.

Variants

NumConversionFailed(String)

Error indicating that a number conversion failed during expansion.

Trait Implementations

impl Debug for ExpansionError

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

Formats the value using the given formatter.

impl Display for ExpansionError

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

Formats the value using the given formatter.

impl Error for ExpansionError

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 ExpansionError

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