Metakey describes the metadata keys that can be stored or queried.

For store

Internally, we will store a flag set of Metakey to check whether we have set some key already.

For query

At user side, we will allow user to query the metadata. If the meta has been stored, we will return directly. If no, we will call stat internally to fetch the metadata.

Variants

Complete

The special metadata key that used to mark this entry already contains all metadata.

Mode

Key for mode.

CacheControl

Key for cache control.

ContentDisposition

Key for content disposition.

ContentLength

Key for content length.

ContentMd5

Key for content md5.

ContentRange

Key for content range.

ContentType

Key for content type.

Etag

Key for etag.

LastModified

Key for last modified.

Version

Key for version.

Trait Implementations

impl<R: Into<FlagSet<Metakey>>> BitAnd<R> for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the & operator.

fn bitand(self, rhs: R) -> Self::Output

Performs the & operation.

impl<R: Into<FlagSet<Metakey>>> BitOr<R> for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the | operator.

fn bitor(self, rhs: R) -> Self::Output

Performs the | operation.

impl<R: Into<FlagSet<Metakey>>> BitXor<R> for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: R) -> Self::Output

Performs the ^ operation.

impl Clone for Metakey

fn clone(&self) -> Metakey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Metakey

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

Formats the value using the given formatter.

impl From<Metakey> for FlagSet<Metakey>

fn from(value: Metakey) -> Self

Converts to this type from the input type.

impl Not for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for Metakey

fn eq(&self, other: &Metakey) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<R: Into<FlagSet<Metakey>>> Rem<R> for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the % operator.

fn rem(self, rhs: R) -> Self::Output

Performs the % operation.

impl<R: Into<FlagSet<Metakey>>> Sub<R> for Metakey

type Output = FlagSet<Metakey>

The resulting type after applying the - operator.

fn sub(self, rhs: R) -> Self::Output

Performs the - operation.

impl Copy for Metakey

impl Eq for Metakey

impl StructuralPartialEq for Metakey
