Enum CompatibilityMode 

pub enum CompatibilityMode {
    None,
    Backward,
    Forward,
    Full,
}

Schema compatibility modes for schema evolution

Defines how strictly new schema versions must be compatible with existing versions.

Variants

None

No compatibility checking - any schema change is allowed

Backward

New schema can read data written with old schema (most common)

• Allows: adding optional fields, removing fields from reader
• Use case: Consumers upgrade before producers

Forward

Old schema can read data written with new schema

• Allows: adding required fields, removing optional fields
• Use case: Producers upgrade before consumers

Full

Both backward and forward compatible (strictest)

• Use case: Critical schemas that need both directions

Implementations

impl CompatibilityMode

pub fn as_str(&self) -> &'static str

Convert to string representation for API calls

Trait Implementations

impl Clone for CompatibilityMode

fn clone(&self) -> CompatibilityMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompatibilityMode

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

Formats the value using the given formatter.

impl Default for CompatibilityMode

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CompatibilityMode

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

impl Copy for CompatibilityMode
