Struct opendal::Metadata

pub struct Metadata { /* private fields */ }

Metadata carries all metadata associated with an path.

Notes

mode and content_length are required metadata that all services should provide during stat operation. But in list operation, a.k.a., Entry’s content length could be None.

Trait Implementations

impl Clone for Metadata

fn clone(&self) -> Metadata

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Metadata

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

Formats the value using the given formatter.

impl PartialEq<Metadata> for Metadata

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