Int(i64)

Integer value.

Float(f64)

Implementations

impl MetadataValue

pub const fn kind(&self) -> Option<MetadataKind>

Returns metadata kind for non-None values.

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 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.
