pub struct MetadataKey { /* private fields */ }

Canonical identifier for metadata fields.

Implementations

impl MetadataKey

pub const fn new(name: &'static str) -> Self

Create a metadata key with a canonical static name.

pub const fn as_str(&self) -> &'static str

Return the raw key name.

pub fn encode(&self, value: impl Display) -> String

Encode a value using the shared delimiter (e.g., “date=2025-01-01”).

pub fn strip<'a>(&self, entry: &'a str) -> Option<&'a str>

Strip the field prefix from a serialized metadata entry.

Trait Implementations

impl Clone for MetadataKey

fn clone(&self) -> MetadataKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataKey

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

Formats the value using the given formatter.

impl PartialEq for MetadataKey

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