Enum MetadataValue 

pub enum MetadataValue {
    None,
    Bool(bool),
    Integer(i64),
    Float(f64),
    String(String),
    Array(Vec<MetadataValue>),
    Object(HashMap<String, MetadataValue>),
}

Trait Implementations

impl Clone for MetadataValue

fn clone(&self) -> MetadataValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetadataValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<HashMap<String, MetadataValue>> for MetadataValue

fn from(value: HashMap<String, MetadataValue>) -> Self

Converts to this type from the input type.

impl From<String> for MetadataValue

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<Vec<MetadataValue>> for MetadataValue

fn from(value: Vec<MetadataValue>) -> Self

Converts to this type from the input type.

impl From<bool> for MetadataValue

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f32> for MetadataValue

fn from(value: f32) -> Self

Converts to this type from the input type.

impl From<f64> for MetadataValue

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i16> for MetadataValue
