Implementations

impl DatabasePrivilegeRowDiff

pub fn from_rows( row1: &DatabasePrivilegeRow, row2: &DatabasePrivilegeRow, ) -> DatabasePrivilegeRowDiff

Calculates the difference between two DatabasePrivilegeRow instances.

pub fn is_empty(&self) -> bool

Returns true if there are no changes in this diff.

pub fn get_privilege_change_by_name( &self, privilege_name: &str, ) -> Result<Option<DatabasePrivilegeChange>>

Retrieves the privilege change for a given privilege name.

fn mappend(&mut self, other: &DatabasePrivilegeRowDiff)

Merges another diff into this one, combining them in a sequential manner.

fn remove_noops(&mut self, from: &DatabasePrivilegeRow)

Removes any no-op changes from the diff, based on the original privilege row.

fn apply(&self, base: &mut DatabasePrivilegeRow)

Trait Implementations

impl Clone for DatabasePrivilegeRowDiff

fn clone(&self) -> DatabasePrivilegeRowDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabasePrivilegeRowDiff

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

Formats the value using the given formatter.

impl Default for DatabasePrivilegeRowDiff

fn default() -> DatabasePrivilegeRowDiff

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DatabasePrivilegeRowDiff

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DatabasePrivilegeRowDiff

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

Formats the value using the given formatter.

impl Ord for DatabasePrivilegeRowDiff

fn cmp(&self, other: &DatabasePrivilegeRowDiff) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DatabasePrivilegeRowDiff

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

impl PartialOrd for DatabasePrivilegeRowDiff

fn partial_cmp(&self, other: &DatabasePrivilegeRowDiff) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DatabasePrivilegeRowDiff

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
