Enum MetadataValueType 

pub enum MetadataValueType {
    Null,
    Bool,
    Number,
    String,
    Array,
    Object,
}

Coarse-grained JSON value types used by crate::MetadataError and inspection APIs.

Metadata stores arbitrary serde_json::Value instances, so it cannot recover the caller’s original Rust type. MetadataValueType is therefore a JSON-level classification, analogous to the stricter data_type() concept in qubit-value, but tailored to an open-ended JSON model.

Variants

Null

JSON null.

Bool

JSON boolean.

Number

JSON number.

String

JSON string.

Array

JSON array.

Object

JSON object.

Implementations

impl MetadataValueType

pub fn of(value: &Value) -> Self

Returns the JSON value type of value.

Trait Implementations

impl Clone for MetadataValueType

fn clone(&self) -> MetadataValueType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataValueType

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

Formats the value using the given formatter.

impl Display for MetadataValueType

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

Formats the value using the given formatter.

impl From<&Value> for MetadataValueType

fn from(value: &Value) -> Self

Converts to this type from the input type.

impl Hash for MetadataValueType

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 PartialEq for MetadataValueType

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