Enum ChangeOperation 

#[non_exhaustive]
pub enum ChangeOperation {
    Insert,
    Update,
    Delete,
}

The type of change operation tracked by SQL Server Change Tracking.

This corresponds to the SYS_CHANGE_OPERATION column in CHANGETABLE results.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Insert

A new row was inserted (I).

Update

An existing row was updated (U).

Delete

A row was deleted (D).

Implementations

impl ChangeOperation

pub fn from_sql(s: &str) -> Option<Self>

Parse a change operation from its single-character SQL Server representation.

Arguments

• s - A string containing ‘I’, ‘U’, or ‘D’

Returns

The parsed ChangeOperation, or None if the input is invalid.

pub const fn as_sql(&self) -> &'static str

Get the SQL Server single-character representation.

pub const fn is_insert(&self) -> bool

Check if this is an insert operation.

pub const fn is_update(&self) -> bool

Check if this is an update operation.

pub const fn is_delete(&self) -> bool

Check if this is a delete operation.

Trait Implementations

impl Clone for ChangeOperation

fn clone(&self) -> ChangeOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChangeOperation

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

Formats the value using the given formatter.

impl Display for ChangeOperation

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

Formats the value using the given formatter.

impl Hash for ChangeOperation

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ChangeOperation

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