Struct TenantDataTransaction 

pub struct TenantDataTransaction<'a> { /* private fields */ }

The application view of a tenant transaction.

This type intentionally exposes no raw transaction handle, commit operation, or option setters. Every key-bearing operation takes a validated data key or range so application callbacks cannot modify kit metadata.

Implementations

impl<'a> TenantDataTransaction<'a>

pub fn set_size_limit(&self, limit: TenantTransactionSizeLimit) -> FdbResult<()>

Applies a validated cluster-side size ceiling before application operations.

pub async fn get( &self, key: TenantDataKey<'_>, snapshot: bool, ) -> FdbResult<Option<FdbSlice>>

Reads an application key, preserving FoundationDB’s retryable error.

pub fn set( &self, key: TenantDataKey<'_>, value: &[u8], ) -> Result<(), TenantDataAccessErrorReason>

Writes a bounded value under an application key.

pub fn clear(&self, key: TenantDataKey<'_>)

Removes one application key. A read-policy attempt aborts the enclosing transaction even though this compatibility method returns no result.

pub fn try_clear( &self, key: TenantDataKey<'_>, ) -> Result<(), TenantDataAccessErrorReason>

Checks the write policy before removing one application key.

pub fn clear_range(&self, range: &TenantDataRange<'_>)

Removes only the validated application interval. A read-policy attempt aborts the enclosing transaction even though this method returns no result.

pub fn try_clear_range( &self, range: &TenantDataRange<'_>, ) -> Result<(), TenantDataAccessErrorReason>

Checks the write policy before clearing an application interval.

pub fn atomic_op( &self, key: TenantDataKey<'_>, parameter: &[u8], mutation: MutationType, ) -> Result<(), TenantDataAccessErrorReason>

Applies an atomic mutation to an application key.

pub fn set_versionstamped_key( &self, key_template: &[u8], value: &[u8], ) -> Result<(), TenantDataAccessErrorReason>

Writes a tuple-layer versionstamped key whose stable prefix is tenant data.

The incomplete versionstamp must lie after the first six key bytes so commit-time substitution cannot move a key into kit metadata or system space.

pub async fn get_range( &self, range: &TenantDataRange<'_>, limit: TenantDataRangeLimit, snapshot: bool, ) -> FdbResult<FdbValues>

Reads one bounded page from an application range.

pub async fn get_range_with_target( &self, range: &TenantDataRange<'_>, limit: TenantDataRangeLimit, target_bytes: TenantDataRangeTargetBytes, snapshot: bool, ) -> FdbResult<FdbValues>

Reads a bounded page with an application-selected response byte target.
