Enum MetaPropertiesError 

#[non_exhaustive]
pub enum MetaPropertiesError {
    Io(Error),
    MalformedEscape,
    InvalidVersion(String),
    UnknownVersion(i32),
    VersionZero,
    NoNodeId,
    NodeIdNotANumber,
    NoClusterId,
    ClusterIdNotAUuid(KafkaUuidError),
    DirectoryIdNotAUuid(KafkaUuidError),
}

Why a meta.properties does not read.

Each message is the message of the exception that Kafka’s PropertiesUtils.readPropertiesFile and MetaProperties.Builder throw for the same file, except where a variant says otherwise.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

The file is there, but it cannot be read.

MalformedEscape

A \u escape is not followed by four hexadecimal digits.

InvalidVersion(String)

version is not a number.

UnknownVersion(i32)

version is a number that Kafka does not define.

VersionZero

The file is version 0, which only a ZooKeeper broker writes. Kafka reads it. krabka does not: it is a krabka message.

NoNodeId

The file has no node.id.

NodeIdNotANumber

node.id is not an int.

NoClusterId

The file has no cluster.id.

ClusterIdNotAUuid(KafkaUuidError)

cluster.id is not a Kafka Uuid. Kafka accepts any string there, so this is a krabka message, in the form of Kafka’s message for directory.id.

DirectoryIdNotAUuid(KafkaUuidError)

directory.id is not a Kafka Uuid.

Trait Implementations

impl Debug for MetaPropertiesError

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

Formats the value using the given formatter.

impl Display for MetaPropertiesError

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

Formats the value using the given formatter.

impl Error for MetaPropertiesError

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 From<Error> for MetaPropertiesError

fn from(source: Error) -> Self

Converts to this type from the input type.
