Struct ConcurrencyKey 

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

A typed concurrency key that ensures runs with the same key don’t run in parallel.

Implementations

impl ConcurrencyKey

pub fn new(key: impl Into<String>) -> Self

Creates a new concurrency key from a string.

In debug builds, panics if the value is empty.

pub fn as_str(&self) -> &str

Returns the key as a string slice.

Trait Implementations

impl Clone for ConcurrencyKey

fn clone(&self) -> ConcurrencyKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcurrencyKey

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

Formats the value using the given formatter.

impl Display for ConcurrencyKey

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

Formats the value using the given formatter.

impl From<&str> for ConcurrencyKey

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for ConcurrencyKey

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for ConcurrencyKey

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 ConcurrencyKey

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