Struct RequestId 

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

A UUID v4 request identifier, typically propagated via the X-Request-Id HTTP header.

Use RequestId::new to generate a fresh identifier, or RequestId::from_str / TryFrom to parse one from an incoming header.

The Display implementation produces the canonical hyphenated UUID string (e.g. 550e8400-e29b-41d4-a716-446655440000).

Implementations

impl RequestId

pub fn new() -> Self

Generate a new random RequestId (UUID v4).

use api_bones::request_id::RequestId;

let id = RequestId::new();
assert_eq!(id.as_uuid().get_version_num(), 4);

pub fn from_uuid(id: Uuid) -> Self

Wrap an existing uuid::Uuid as a RequestId.

use api_bones::request_id::RequestId;

let id = RequestId::from_uuid(uuid::Uuid::nil());
assert_eq!(id.to_string(), "00000000-0000-0000-0000-000000000000");

pub fn as_uuid(&self) -> Uuid

Return the inner uuid::Uuid.

pub fn header_name(&self) -> &'static str

The canonical HTTP header name for this identifier: X-Request-Id.

pub fn as_str(&self) -> String

Return the hyphenated UUID string representation.

Trait Implementations

impl Clone for RequestId

fn clone(&self) -> RequestId

Returns a duplicate 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

Available on crate feature serde only.

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

Deserialize this value from the given Serde deserializer.

impl Display for RequestId

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

Formats the value using the given formatter.

impl From<RequestId> for Uuid

fn from(r: RequestId) -> Self

Converts to this type from the input type.

impl From<Uuid> for RequestId

fn from(id: Uuid) -> Self

Converts to this type from the input type.

impl FromStr for RequestId

type Err = RequestIdError

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 HeaderId for RequestId

Available on crate feature std only.

const HEADER_NAME: &'static str = "X-Request-Id"

The canonical HTTP header name for this type.

fn as_str(&self) -> Cow<'_, str>

Return the string representation of this header value.

impl PartialEq for RequestId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for RequestId

type Error = RequestIdError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for RequestId

type Error = RequestIdError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for RequestId

impl Eq for RequestId
