Struct StatusCode 

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

A NATS status code

Constants are provided for known and accurately status codes within the NATS Server.

Values are guaranteed to be in range 100..1000.

Implementations

impl StatusCode

pub const IDLE_HEARTBEAT: StatusCode

The Jetstream consumer hearthbeat timeout has been reached with no new messages to deliver

See ADR-9.

pub const OK: StatusCode

The request has successfully been sent

pub const NOT_FOUND: StatusCode

The requested Jetstream resource doesn’t exist

pub const TIMEOUT: StatusCode

The pull consumer batch reached the timeout

pub const NO_RESPONDERS: StatusCode

The request was sent to a subject that does not appear to have any subscribers listening

pub fn from_ascii_bytes(buf: &[u8]) -> Result<Self, StatusCodeError>

Decodes a status code from a slice of ASCII characters.

The ASCII representation is expected to be in the form of "NNN", where N is a numeric digit.

Errors

It returns an error if the slice of bytes does not contain a valid status code.

Trait Implementations

impl Clone for StatusCode

fn clone(&self) -> StatusCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StatusCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StatusCode

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

Deserialize this value from the given Serde deserializer.

impl Display for StatusCode

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

Formats the value using the given formatter.

impl From<StatusCode> for u16

fn from(value: StatusCode) -> Self

Converts to this type from the input type.

impl FromStr for StatusCode

type Err = StatusCodeError

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 Ord for StatusCode

fn cmp(&self, other: &StatusCode) -> 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,

Restrict a value to a certain interval.

impl PartialEq for StatusCode

fn eq(&self, other: &StatusCode) -> 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 StatusCode

fn partial_cmp(&self, other: &StatusCode) -> 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.

impl Serialize for StatusCode

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

Serialize this value into the given Serde serializer.

impl TryFrom<u16> for StatusCode

type Error = StatusCodeError

The type returned in the event of a conversion error.

fn try_from(value: u16) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for StatusCode
