Enum LuaErrorKind 

pub enum LuaErrorKind {
    Runtime,
    Syntax,
    InstrBudget,
    MemoryCap,
    Native,
    OutOfMemory,
    Type,
}

Classification of the most recent error raised on a Vm.

Embedders switch on this to decide whether to retry (InstrBudget, MemoryCap), report (Runtime, Syntax), or treat as fatal (Native, OutOfMemory). Default is LuaErrorKind::Runtime.

Variants

Runtime

Generic Lua runtime error (error(...), type errors, missing global, etc.). The default classification.

Syntax

Source did not parse (lexer or parser rejected the input).

InstrBudget

vm.set_instr_budget(Some(N)) budget exhausted mid-call.

MemoryCap

vm.set_memory_cap(Some(N)) cap exceeded during allocation.

Native

A NativeFn callback returned Err(LuaError) (host-side error).

OutOfMemory

Allocation failed (typically only on cap exhaustion in luna).

Type

error raised at a type boundary (e.g. arithmetic on a table).

Trait Implementations

impl Clone for LuaErrorKind

fn clone(&self) -> LuaErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LuaErrorKind

impl Debug for LuaErrorKind

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

Formats the value using the given formatter.

impl Default for LuaErrorKind

fn default() -> LuaErrorKind

Returns the “default value” for a type.

impl Display for LuaErrorKind

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

Formats the value using the given formatter.

impl Eq for LuaErrorKind

impl Hash for LuaErrorKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LuaErrorKind

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