Enum Compatibility 

pub enum Compatibility {
    Exact,
    Forward {
        reader_version: u32,
        writer_version: u32,
    },
    Backward {
        reader_version: u32,
        writer_version: u32,
    },
    Unknown {
        writer_version: String,
    },
}

Outcome of a schema compatibility check.

Variants

Exact

Versions match exactly.

Forward

Reader is newer than writer — forward compatible (reader can read older data).

Fields

reader_version: u32

writer_version: u32

Backward

Writer is newer than reader — incompatible (needs migration).

Fields

reader_version: u32

writer_version: u32

Unknown

Version string doesn’t match expected format for this schema kind.

Fields

writer_version: String

Implementations

impl Compatibility

pub fn is_compatible(&self) -> bool

Whether the reader can process data from the writer.

Trait Implementations

impl Clone for Compatibility

fn clone(&self) -> Compatibility

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Compatibility

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

Formats the value using the given formatter.

impl Display for Compatibility

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

Formats the value using the given formatter.

impl PartialEq for Compatibility

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