Struct StatusCode

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

An NATS status code.

Constants are provided for known status codes.

Status code values in the range 100-999 (inclusive) are supported by this type. Values in the range 100-599 are semantically classified by the most significant digit. See StatusCode::is_success, etc.

Examples

use async_nats::StatusCode;

assert_eq!(StatusCode::OK.as_u16(), 200);
assert!(StatusCode::OK.is_success());

Implementations

impl StatusCode

pub fn from_u16(src: u16) -> Result<StatusCode, InvalidStatusCode>

Converts a u16 to a status code.

The function validates the correctness of the supplied u16. It must be greater or equal to 100 and less than 1000.

Example

use async_nats::status::StatusCode;

let ok = StatusCode::from_u16(200).unwrap();
assert_eq!(ok, StatusCode::OK);

let err = StatusCode::from_u16(99);
assert!(err.is_err());

let err = StatusCode::from_u16(1000);
assert!(err.is_err());

pub fn from_bytes(src: &[u8]) -> Result<StatusCode, InvalidStatusCode>

Converts a &[u8] to a status code

pub fn as_u16(&self) -> u16

Returns the u16 corresponding to this StatusCode.

Example

let status = async_nats::StatusCode::OK;
assert_eq!(status.as_u16(), 200);

pub fn is_informational(&self) -> bool

Check if status is within 100-199.

pub fn is_success(&self) -> bool

Check if status is within 200-299.

pub fn is_redirection(&self) -> bool

Check if status is within 300-399.

pub fn is_client_error(&self) -> bool

Check if status is within 400-499.

pub fn is_server_error(&self) -> bool

Check if status is within 500-599.
