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.

impl From<&str> for MetadataValue

fn from(value: &str) -> 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<&str>> for MetadataValue

fn from(value: Vec<&str>) -> Self

Converts to this type from the input type.

impl From<Vec<String>> for MetadataValue

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

Converts to this type from the input type.

impl PartialEq for MetadataValue

fn eq(&self, other: &MetadataValue) -> 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 Serialize for MetadataValue

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
