Struct DataTableLockVersion 

#[non_exhaustive]
pub struct DataTableLockVersion {
    pub data_table: Option<String>,
    pub attribute: Option<String>,
    pub primary_values: Option<String>,
    pub value: Option<String>,
}

Contains lock version information for different levels of a data table hierarchy. Used for optimistic locking to prevent concurrent modification conflicts. Each component has its own lock version that changes when that component is modified.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

data_table: Option<String>

The lock version for the data table itself. Used for optimistic locking and table versioning. Changes with each update to the table's metadata or structure.

attribute: Option<String>

The lock version for a specific attribute. When the ValueLockLevel is ATTRIBUTE, this version changes when any value for the attribute changes. For other lock levels, it only changes when the attribute's properties are directly updated.

primary_values: Option<String>

The lock version for a specific set of primary values (record). This includes the default record even if the table does not have any primary attributes. Used for record-level locking.

value: Option<String>

The lock version for a specific value. Changes each time the individual value is modified. Used for the finest-grained locking control.

Implementations

impl DataTableLockVersion

pub fn data_table(&self) -> Option<&str>

The lock version for the data table itself. Used for optimistic locking and table versioning. Changes with each update to the table's metadata or structure.

pub fn attribute(&self) -> Option<&str>

The lock version for a specific attribute. When the ValueLockLevel is ATTRIBUTE, this version changes when any value for the attribute changes. For other lock levels, it only changes when the attribute's properties are directly updated.

pub fn primary_values(&self) -> Option<&str>

The lock version for a specific set of primary values (record). This includes the default record even if the table does not have any primary attributes. Used for record-level locking.

pub fn value(&self) -> Option<&str>

The lock version for a specific value. Changes each time the individual value is modified. Used for the finest-grained locking control.

impl DataTableLockVersion

pub fn builder() -> DataTableLockVersionBuilder

Creates a new builder-style object to manufacture DataTableLockVersion.

Trait Implementations

impl Clone for DataTableLockVersion

fn clone(&self) -> DataTableLockVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataTableLockVersion

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

Formats the value using the given formatter.

impl PartialEq for DataTableLockVersion

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