Enum mlua::prelude::LuaValue [−][src]
pub enum LuaValue<'lua> { Nil, Boolean(bool), LightUserData(LightUserData), Integer(Integer), Number(Number), String(String<'lua>), Table(Table<'lua>), Function(Function<'lua>), Thread(Thread<'lua>), UserData(AnyUserData<'lua>), Error(Error), }
Expand description
A dynamically typed Lua value. The String
, Table
, Function
, Thread
, and UserData
variants contain handle types into the internal Lua state. It is a logic error to mix handle
types between separate Lua
instances, and doing so will result in a panic.
Variants
Expand description
The Lua value nil
.
Boolean(bool)
Expand description
The Lua value true
or false
.
LightUserData(LightUserData)
Expand description
A “light userdata” object, equivalent to a raw pointer.
Integer(Integer)
Expand description
An integer number.
Any Lua number convertible to a Integer
will be represented as this variant.
Number(Number)
Expand description
A floating point number.
String(String<'lua>)
Expand description
An interned string, managed by Lua.
Unlike Rust strings, Lua strings may not be valid UTF-8.
Table(Table<'lua>)
Expand description
Reference to a Lua table.
Function(Function<'lua>)
Expand description
Reference to a Lua function (or closure).
Thread(Thread<'lua>)
Expand description
Reference to a Lua thread (or coroutine).
UserData(AnyUserData<'lua>)
Expand description
Reference to a userdata object that holds a custom type which implements UserData
.
Special builtin userdata types will be represented as other Value
variants.
Error(Error)
Expand description
Error
is a special builtin userdata type. When received from Lua it is implicitly cloned.
Implementations
impl<'lua> Value<'lua>
[src]
impl<'lua> Value<'lua>
[src]pub fn type_name(&self) -> &'static str
[src]
pub fn equals<T: AsRef<Self>>(&self, other: T) -> Result<bool>
[src]
pub fn equals<T: AsRef<Self>>(&self, other: T) -> Result<bool>
[src]Compares two values for equality.
Equality comparisons do not convert strings to numbers or vice versa. Tables, Functions, Threads, and Userdata are compared by reference: two objects are considered equal only if they are the same object.
If Tables or Userdata have __eq
metamethod then mlua will try to invoke it.
The first value is checked first. If that value does not define a metamethod
for __eq
, then mlua will check the second value.
Then mlua calls the metamethod with the two values as arguments, if found.
