Struct rlua::LuaTable

pub struct LuaTable<'lua>(_);

Handle to an an internal lua table

Methods

impl<'lua> LuaTable<'lua>

fn set<K: ToLua<'lua>, V: ToLua<'lua>>(&self, key: K, value: V) -> LuaResult<()>

fn get<K: ToLua<'lua>, V: FromLua<'lua>>(&self, key: K) -> LuaResult<V>

fn has<K: ToLua<'lua>>(&self, key: K) -> LuaResult<bool>

Shorthand for checking whether get(key) is nil

fn raw_set<K: ToLua<'lua>, V: ToLua<'lua>>(
    &self,
    key: K,
    value: V
) -> LuaResult<()>

Set a field in the table, without invoking metamethods

fn raw_get<K: ToLua<'lua>, V: FromLua<'lua>>(&self, key: K) -> LuaResult<V>

Get a field in the table, without invoking metamethods

fn length(&self) -> LuaResult<LuaInteger>

Equivalent to the result of the lua '#' operator.

fn raw_length(&self) -> LuaResult<LuaInteger>

Equivalent to the result of the lua '#' operator, without invoking the __len metamethod.

fn for_each_pair<K, V, F>(&self, f: F) -> LuaResult<()> where
    K: FromLua<'lua>,
    V: FromLua<'lua>,
    F: FnMut(K, V), 

Loop over each key, value pair in the table

fn for_each_array_value<V: FromLua<'lua>, F: FnMut(V)>(
    &self,
    f: F
) -> LuaResult<()>

Loop over the table, strictly interpreting the table as an array, and fail if it is not a proper lua array.

fn pairs<K: FromLua<'lua>, V: FromLua<'lua>>(&self) -> LuaResult<Vec<(K, V)>>

Collect all the pairs in the table into a Vec

fn array_values<V: FromLua<'lua>>(&self) -> LuaResult<Vec<V>>

Collect all the values in an array-like table into a Vec
