Struct object_store::Attributes

pub struct Attributes(/* private fields */);

Additional attributes of an object

Attributes can be specified in PutOptions and retrieved from APIs returning GetResult.

Unlike ObjectMeta, Attributes are not returned by listing APIs

Implementations

impl Attributes

pub fn new() -> Self

Create a new empty Attributes

pub fn with_capacity(capacity: usize) -> Self

Create a new Attributes with space for capacity Attribute

pub fn insert( &mut self, key: Attribute, value: AttributeValue, ) -> Option<AttributeValue>

Insert a new Attribute, AttributeValue pair

Returns the previous value for key if any

pub fn get(&self, key: &Attribute) -> Option<&AttributeValue>

Returns the AttributeValue for key if any

pub fn remove(&mut self, key: &Attribute) -> Option<AttributeValue>

Removes the AttributeValue for key if any

pub fn iter(&self) -> AttributesIter<'_>

Returns an AttributesIter over this

pub fn len(&self) -> usize

Returns the number of Attribute in this collection

pub fn is_empty(&self) -> bool

Returns true if this contains no Attribute

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Attributes

Returns the “default value” for a type.

impl From<Attributes> for PutMultipartOpts

fn from(attributes: Attributes) -> Self

Converts to this type from the input type.

impl From<Attributes> for PutOptions

fn from(attributes: Attributes) -> Self

Converts to this type from the input type.

impl<K, V> FromIterator<(K, V)> for Attributes

where K: Into<Attribute>, V: Into<AttributeValue>,

fn from_iter<T: IntoIterator<Item = (K, V)>>(iter: T) -> Self

Creates a value from an iterator.

impl<'a> IntoIterator for &'a Attributes

type Item = (&'a Attribute, &'a AttributeValue)

The type of the elements being iterated over.

type IntoIter = AttributesIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for Attributes

fn eq(&self, other: &Attributes) -> 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 Eq for Attributes

impl StructuralPartialEq for Attributes
