Struct aws_smithy_runtime_api::client::identity::IdentityCachePartition

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

Cache partition key for identity caching.

Identities need cache partitioning because a single identity cache is used across multiple identity providers across multiple auth schemes. In addition, a single auth scheme may have many different identity providers due to operation-level config overrides.

This partition must be respected when retrieving from the identity cache and should be part of the cache key.

Calling IdentityCachePartition::new will create a new globally unique cache partition key, and the SharedIdentityResolver will automatically create and store a partion on construction. Thus, every configured identity resolver will be assigned a unique partition.

Implementations

impl IdentityCachePartition

pub fn new() -> Self

Create a new globally unique cache partition key.

pub fn new_for_tests(value: usize) -> IdentityCachePartition

Helper for unit tests to create an identity cache partition with a known value.

Trait Implementations

impl Clone for IdentityCachePartition

fn clone(&self) -> IdentityCachePartition

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IdentityCachePartition

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

Formats the value using the given formatter.

impl Hash for IdentityCachePartition

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 Ord for IdentityCachePartition

fn cmp(&self, other: &IdentityCachePartition) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for IdentityCachePartition

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

impl PartialOrd for IdentityCachePartition

fn partial_cmp(&self, other: &IdentityCachePartition) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
