Struct IdempotencyKey 

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

An idempotency key for a scraping operation.

Based on ULID for lexicographic ordering and embedded timestamp.

Example

use stygian_graph::domain::idempotency::IdempotencyKey;

let key = IdempotencyKey::generate();
let encoded = key.to_string();
let decoded: IdempotencyKey = encoded.parse().unwrap();
assert_eq!(key, decoded);

Implementations

impl IdempotencyKey

pub fn generate() -> Self

Generate a new unique idempotency key.

pub fn parse(s: &str) -> Result<Self, DecodeError>

Parse an idempotency key from its string representation.

Errors

Returns an error if the string is not a valid ULID.

pub fn cache_key(&self) -> String

The cache key used to store this record.

Trait Implementations

impl Clone for IdempotencyKey

fn clone(&self) -> IdempotencyKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IdempotencyKey

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

Formats the value using the given formatter.

impl Default for IdempotencyKey

fn default() -> Self

Returns the “default value” for a type.

impl Display for IdempotencyKey

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

Formats the value using the given formatter.

impl FromStr for IdempotencyKey

type Err = DecodeError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for IdempotencyKey

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 IdempotencyKey

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