Trait Implementations

impl Clone for Null

fn clone(&self) -> Null

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Null

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

Formats the value using the given formatter.

impl Hash for Null

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<L> LuaRead<L> for Null

where L: AsLua,

fn lua_read_at_position(lua: L, index: NonZeroI32) -> ReadResult<Self, L>

Reads the data from Lua at a given position.

fn lua_read_at_maybe_zero_position(lua: L, index: i32) -> ReadResult<Self, L>

fn n_values_expected() -> i32

fn lua_read(lua: L) -> ReadResult<Self, L>

Reads the data from Lua.

impl Ord for Null

fn cmp(&self, other: &Null) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Null

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

impl PartialOrd for Null

fn partial_cmp(&self, other: &Null) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<L> Push<L> for Null

where L: AsLua,

type Err = Void

Error that can happen when pushing a value.

fn push_to_lua(&self, lua: L) -> Result<PushGuard<L>, (Void, L)>

Pushes the value on the top of the stack.

fn push_no_err(&self, lua: L) -> PushGuard<L>

where <Self as Push<L>>::Err: Into<Void>,

Same as push_to_lua but can only succeed and is only available if Err implements Into<Void>.

impl<L> PushInto<L> for Null

where L: AsLua,

type Err = Void

fn push_into_lua(self, lua: L) -> Result<PushGuard<L>, (Void, L)>

Push the value into lua by value

fn push_into_no_err(self, lua: L) -> PushGuard<L>

where Self: Sized, <Self as PushInto<L>>::Err: Into<Void>,

Same as push_into_lua but can only succeed and is only available if Err implements Into<Void>.

impl Copy for Null

impl Eq for Null

impl<L> PushOne<L> for Null

where L: AsLua,

impl<L> PushOneInto<L> for Null

where L: AsLua,
