Implementations

impl Value

    T: Into<Scalar>,

Create as a Scalar.

pub fn array<I>(iter: I) -> Valuewhere
    I: IntoIterator<Item = Value>,

Create as an Array.

pub fn nil() -> Value

Create as nothing.

pub fn to_str(&self) -> Cow<'_, str>

Interpret as a string.

pub fn as_scalar(&self) -> Option<&Scalar>

Extracts the scalar value if it is a scalar.

pub fn is_scalar(&self) -> bool

Tests whether this value is a scalar

pub fn as_array(&self) -> Option<&Vec<Value, Global>>

Extracts the array value if it is an array.

pub fn as_array_mut(&mut self) -> Option<&mut Vec<Value, Global>>

Extracts the array value if it is an array.

pub fn is_array(&self) -> bool

Tests whether this value is an array

pub fn as_object(
    &self
) -> Option<&HashMap<Cow<'static, str>, Value, RandomState>>

Extracts the object value if it is a object.

pub fn as_object_mut(
    &mut self
) -> Option<&mut HashMap<Cow<'static, str>, Value, RandomState>>

Extracts the object value if it is a object.

pub fn is_object(&self) -> bool

Tests whether this value is an object

pub fn is_nil(&self) -> bool

pub fn is_truthy(&self) -> bool

Evaluate using Liquid “truthiness”

pub fn is_default(&self) -> bool

Whether a default constructed value.

pub fn type_name(&self) -> &'static str

Report the data type (generally for error reporting).

    I: Into<&'i Scalar>,

Access a contained Value.

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<(), Error>

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Value

fn deserialize<__D>(
    __deserializer: __D
) -> Result<Value, <__D as Deserializer<'de>>::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl PartialEq<Value> for Value

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

impl PartialOrd<Value> for Value

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Value

fn serialize<__S>(
    &self,
    __serializer: __S
) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Value
