Enum IsolationLevel 

#[non_exhaustive]
pub enum IsolationLevel {
    ReadUncommitted,
    ReadCommitted,
}

Isolation level used to control which records are visible to a consumer when reading from a topic.

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.

ReadUncommitted

Read records including those from in-flight (uncommitted) transactions.

ReadCommitted

Skip records from in-flight (uncommitted) transactions and only read records up to the last stable offset.

Implementations

impl IsolationLevel

pub fn id(&self) -> u8

Returns the wire-protocol id used to encode this isolation level.

Translated from Java’s byte id().

pub fn for_id(id: u8) -> Result<Self, Error>

Returns the IsolationLevel for the given wire-protocol id.

Translated from Java’s forId(byte id). Returns Error::LocalIllegalArgument for unknown ids; the Java implementation throws IllegalArgumentException.

Trait Implementations

impl Clone for IsolationLevel

fn clone(&self) -> IsolationLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IsolationLevel

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

Formats the value using the given formatter.

impl Display for IsolationLevel

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

Matches Java’s toString() which lower-cases the enum name.

impl Hash for IsolationLevel

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IsolationLevel

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