Struct MetadataEntry 

#[non_exhaustive]
pub struct MetadataEntry {
    pub name: String,
    pub value: Option<Vec<u8>>,
}

A single metadata entry from a METADATA response (RFC 5464 Section 4.4).

Each entry has a name (e.g. /private/comment) and an optional value. A None value indicates the entry does not exist or has been deleted.

RFC 5464 Section 5 formal syntax: value = nstring / literal8. The literal8 form (~{n}\r\n<data>) allows arbitrary binary octets, so the value is stored as raw bytes rather than a UTF-8 string.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Entry name (e.g. /private/comment, /shared/vendor/foo) (RFC 5464 Section 3.2).

value: Option<Vec<u8>>

Entry value as raw bytes, or None if the entry does not exist (RFC 5464 Section 4.4).

RFC 5464 Section 5: value = nstring / literal8 — values may contain arbitrary binary data via the literal8 syntax, so Vec<u8> is used instead of String to preserve binary fidelity.

Trait Implementations

impl Clone for MetadataEntry

fn clone(&self) -> MetadataEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataEntry

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

Formats the value using the given formatter.

impl Default for MetadataEntry

fn default() -> MetadataEntry

Returns the “default value” for a type.

impl Hash for MetadataEntry

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 MetadataEntry

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