Struct scratchstack_http_framework::RequestId

pub struct RequestId { /* private fields */ }

AWS request id implementation.

This implementation abuses the UUID format the embed a timestamp in the UUID to make it easier to track down the request in the logs. This timestamp has a resolution of 1s and is based on the system clock, so it’s not guaranteed to be unique; thus, a random number is also embedded in the UUID.

Implementations

impl RequestId

pub fn new() -> Self

Create a new request id from the current system time and a random number.

pub fn from_timestamp_and_random(unix_timestamp: i64, random: u64) -> Self

Create a new request id from the given timestamp, in seconds from the Unix epoch (January 1, 1970 at 00:00:00 UTC) and random number.

pub fn from_datetime_and_random<Tz: TimeZone>(
    datetime: DateTime<Tz>,
    random: u64
) -> Self

Create a new request id from the given timestamp and random number.

pub fn from_timestamp(unix_timestamp: i64) -> Self

Create a new request id from the given timestamp, in seconds from the Unix epoch (January 1, 1970 at 00:00:00 UTC).

pub fn from_datetime<Tz: TimeZone>(datetime: DateTime<Tz>) -> Self

Create a new request id from the given timestamp.

pub fn unix_timestamp(&self) -> u64

Returns the Unix timestamp, in seconds from the Unix epoch (January 1, 1970 at 00:00:00 UTC), embedded in this request id.

pub fn datetime(&self) -> DateTime<Utc>

Returns the timestamp embedded in this request id.

pub fn uuid(&self) -> Uuid

Returns this request id as a UUID.

Trait Implementations

impl Clone for RequestId

fn clone(&self) -> RequestId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RequestId

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

Formats the value using the given formatter.

impl Default for RequestId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RequestId

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where
    D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for RequestId

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

Formats the value using the given formatter.

impl FromStr for RequestId

type Err = Error

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 RequestId

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<RequestId> for RequestId

fn eq(&self, other: &RequestId) -> 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 Serialize for RequestId

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where
    S: Serializer,

Serialize this value into the given Serde serializer.
