Implementations

impl LuaState

pub unsafe fn new() -> Result<Self, LuaError>

pub unsafe fn is_client(&self) -> bool

Returns whether this is the clientside Lua state or not.

pub unsafe fn is_server(&self) -> bool

Returns whether this is the serverside Lua state or not.

pub unsafe fn is_menu(&self) -> bool

Returns whether this is the menu Lua state or not.

pub unsafe fn get_binary_string(&self, index: i32) -> Option<&[u8]>

Returns the Lua string as a slice of bytes.

WARNING: This will CHANGE the type of the value at the given index to a string.

Returns None if the value at the given index is not convertible to a string.

pub unsafe fn get_string(&self, index: i32) -> Option<Cow<'_, str>>

Returns the Lua string as a Rust UTF-8 String.

WARNING: This will CHANGE the type of the value at the given index to a string.

Returns None if the value at the given index is not convertible to a string.

This is a lossy operation, and will replace any invalid UTF-8 sequences with the Unicode replacement character. See the documentation for String::from_utf8_lossy for more information.

If you need raw data, use get_binary_string.

pub unsafe fn get_type(&self, index: i32) -> &str

Returns the name of the type of the value at the given index.

pub unsafe fn get_top(&self) -> i32

pub unsafe fn reference(&self) -> LuaReference

Pops the stack, inserts the value into the registry table, and returns the registry index of the value.

Use from_reference with the reference index to push the value back onto the stack.

Use dereference to free the reference from the registry table.

pub unsafe fn dereference(&self, ref: LuaReference)

pub unsafe fn from_reference(&self, ref: LuaReference)

pub unsafe fn is_nil(&self, index: i32) -> bool

pub unsafe fn is_function(&self, index: i32) -> bool

pub unsafe fn is_table(&self, index: i32) -> bool

pub unsafe fn is_boolean(&self, index: i32) -> bool

pub unsafe fn remove(&self, index: i32)

pub unsafe fn to_thread(&self, index: i32) -> State

pub unsafe fn pcall(&self, nargs: i32, nresults: i32, errfunc: i32) -> i32

pub unsafe fn pcall_ignore(&self, nargs: i32, nresults: i32) -> bool

Same as pcall, but ignores any runtime error and calls ErrorNoHaltWithStack instead with the error message.

Returns whether the execution was successful.

pub unsafe fn load_string(&self, src: LuaString) -> Result<(), LuaError>

pub unsafe fn load_buffer(
    &self,
    buff: &[u8],
    name: LuaString
) -> Result<(), LuaError>

pub unsafe fn push_registry(&self)

pub unsafe fn push_string(&self, data: &str)

pub unsafe fn push_binary_string(&self, data: &[u8])

pub unsafe fn push_function(&self, func: LuaFunction)

pub unsafe fn set_table(&self, index: i32)

pub unsafe fn set_field(&self, index: i32, k: LuaString)

pub unsafe fn get_global(&self, name: LuaString)

pub unsafe fn set_global(&self, name: LuaString)

pub unsafe fn call(&self, nargs: i32, nresults: i32)

WARNING: Any Lua errors caused by calling the function will longjmp and prevent any further execution of your code.

To workaround this, use pcall_ignore, which will call ErrorNoHaltWithStack instead and allow your code to continue executing.

pub unsafe fn insert(&self, index: i32)

pub unsafe fn create_table(&self, seq_n: i32, hash_n: i32)

Creates a new table and pushes it to the stack. seq_n is a hint as to how many sequential elements the table may have. hash_n is a hint as to how many non-sequential/hashed elements the table may have. Lua may use these hints to preallocate memory.

pub unsafe fn new_table(&self)

Creates a new table and pushes it to the stack without memory preallocation hints. Equivalent to create_table(0, 0)

pub unsafe fn get_table(&self, index: i32)

pub unsafe fn coroutine_exchange(&self, target_thread: State, n: i32)

    &self,
    data: T,
    metatable: Option<i32>
) -> *mut T

pub unsafe fn error<S: AsRef<str>>(&self, msg: S) -> !

    what: LuaString
) -> Result<(), ()>

pub unsafe fn debug_getinfo_from_stack(
