Enum StreamError 

pub enum StreamError {
    AlreadyExists {
        scope: StreamScope,
        name: String,
    },
    NotFound {
        scope: StreamScope,
        name: String,
    },
    CrossTenantDenied {
        principal_tenant: Option<String>,
        target: StreamScope,
        stream: String,
    },
}

Errors surfaced by the stream registry.

name: String

NotFound

An op targeted a stream that has not been created.

Trait Implementations

impl Debug for StreamError

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

Formats the value using the given formatter.

impl Display for StreamError

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

Formats the value using the given formatter.

impl Error for StreamError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for StreamError

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