Struct MigrationRowOp 

pub struct MigrationRowOp { /* private fields */ }

MigrationRowOp

Public migration row operation DTO used to build explicit migration steps. This DTO mirrors commit row-op payload shape without exposing commit internals. Migration execution converts these DTOs into commit marker row operations.

Implementations

impl MigrationRowOp

pub fn new( entity_path: impl Into<String>, key: Vec<u8>, before: Option<Vec<u8>>, after: Option<Vec<u8>>, schema_fingerprint: [u8; 16], ) -> Result<Self, InternalError>

Construct one validated migration row operation DTO.

The constructor is the only public construction boundary for migration row operations. It validates the runtime entity path, rejects no-op row operations, and decodes the raw data key once before the operation enters the lower migration engine.

pub const fn entity_path(&self) -> &str

Return the runtime entity path resolved by commit runtime hooks.

pub const fn key(&self) -> &[u8]

Borrow the encoded raw data key bytes for the target row identity.

pub fn before(&self) -> Option<&[u8]>

Borrow the optional encoded before-image row payload.

pub fn after(&self) -> Option<&[u8]>

Borrow the optional encoded after-image row payload.

pub const fn schema_fingerprint(&self) -> [u8; 16]

Return the schema fingerprint expected by commit prepare/replay.
