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 CONFLICT: StatusCode

The pull consumer batch has been terminated by the server

This status code is used by the NATS Server for multiple unrelated conditions, which can only be told apart via ServerMessage::status_description. Known descriptions include Batch Completed, Server Shutdown, Leadership Change, Consumer Deleted, Consumer is push based, Exceeded MaxRequestBatch of %d, Exceeded MaxRequestExpires of %v, Exceeded MaxRequestMaxBytes of %v, Exceeded MaxWaiting and Message Size Exceeds MaxBytes.

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.
