Struct SymbolTableError 

pub struct SymbolTableError {
    pub key: String,
    pub conflict: String,
}

Error returned when a SymbolTable::set call conflicts with an existing entry.

For example, setting "A.B.C" when "A.B" is already a scalar value.

Fields

key: String

conflict: String

Trait Implementations

impl Clone for SymbolTableError

fn clone(&self) -> SymbolTableError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SymbolTableError

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

Formats the value using the given formatter.

impl Display for SymbolTableError

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

Formats the value using the given formatter.

impl Error for SymbolTableError

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<SymbolTableError> for ExpressionError

fn from(e: SymbolTableError) -> Self

Bubble a symbol-table conflict up as an ExpressionError::Other.

The full SymbolTableError message is preserved verbatim so callers can still see which key was being set and what it conflicted with. Call sites that have an AST node available can further attach .with_node(...) / .with_span(...) for caret-annotated output.
