Struct MetadataEntry 

pub struct MetadataEntry<'a> {
    pub key: Cow<'a, str>,
    pub value: MetadataValue<'a>,
    pub flags: MetadataFlags,
}

A single metadata entry with a key, value, and flags.

Uses Cow for the key so entries can be borrowed (from wire data) or owned.

Fields

key: Cow<'a, str>

value: MetadataValue<'a>

flags: MetadataFlags

Implementations

impl<'a> MetadataEntry<'a>

pub fn str(key: impl Into<Cow<'a, str>>, value: impl Into<Cow<'a, str>>) -> Self

Create a string metadata entry with no flags.

pub fn u64(key: impl Into<Cow<'a, str>>, value: u64) -> Self

Create a u64 metadata entry with no flags.

pub fn bytes( key: impl Into<Cow<'a, str>>, value: impl Into<Cow<'a, [u8]>>, ) -> Self

Create a bytes metadata entry with no flags.

pub fn with_flags(self, flags: MetadataFlags) -> Self

Set flags on this entry.

pub fn into_owned(self) -> MetadataEntry<'static>

Convert to a 'static lifetime by cloning any borrowed data.

Trait Implementations

impl<'a> Clone for MetadataEntry<'a>

fn clone(&self) -> MetadataEntry<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MetadataEntry<'a>

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

Formats the value using the given formatter.

impl<'a, 'ʄ> Facet<'ʄ> for MetadataEntry<'a>

where 'a: 'ʄ, 'ʄ: 'a,

const SHAPE: &'static Shape

The shape of this type, including: whether it’s a Struct, an Enum, something else?

impl<'a> PartialEq for MetadataEntry<'a>

fn eq(&self, other: &MetadataEntry<'a>) -> 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.
