Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Display for Value

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

Formats the value using the given formatter.

impl Extend<Value> for Table

fn extend<T: IntoIterator<Item = Value>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<Value> for String

fn from(value: Value) -> Self

Converts to this type from the input type.

impl From<Value> for bool

fn from(value: Value) -> Self

Converts to this type from the input type.

impl FromIterator<Value> for Table

fn from_iter<T: IntoIterator<Item = Value>>(iter: T) -> Self

Creates a value from an iterator.

impl Hash for Value

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 Index<&Value> for Table

type Output = Value

The returned type after indexing.

fn index(&self, index: &Value) -> &Self::Output

Performs the indexing (container[index]) operation.

impl PartialEq<Value> for Value

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

unsafe fn trace(&self)

Marks all contained Gcs.

unsafe fn marked(&self) -> bool

Is this object marked.

impl TryFrom<Value> for f64

type Error = BuiltinError

Performs the conversion.

impl TryFrom<Value> for i64

type Error = BuiltinError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>
