Enum JitError

    UnknownFunction {
        name: String,
        arity: u8,
    },

}

The primary error type for the tabulon crate.

Variants

Parse(String)

An error occurred while parsing the expression string.

UnknownIdent(String)

The expression contained an identifier (variable) that was not recognized by the resolver.

UnknownFunction

The expression tried to call a function that was not registered with the engine.

Fields

name: String

arity: u8

FunctionExists

An attempt was made to register a function with a name and arity that already exists.

Fields

name: String

arity: u8

Invalidated

An attempt was made to evaluate an expression after the underlying JIT memory was freed. Call Tabula::free_memory invalidates all previously compiled expressions.

Internal(String)

An unexpected internal error occurred within the JIT compiler or engine. These errors often indicate a bug in tabulon itself.

ValuesLen

The number of values provided for evaluation did not match the number of variables in the expression.

Fields

expected: usize

got: usize

Trait Implementations

impl Debug for JitError

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

Formats the value using the given formatter.

impl Display for JitError

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

Formats the value using the given formatter.

impl Error for JitError

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>)
