    Select,
    Insert,
    Update,
    Delete,
}

The command kind a policy applies to.

Variants

All

FOR ALL — covers SELECT, INSERT, UPDATE, DELETE.

Select

FOR SELECT.

Insert

FOR INSERT.

Update

FOR UPDATE.

Delete

FOR DELETE.

Implementations

impl PolicyCommand

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

SQL keyword used in CREATE POLICY rendering.

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

pg_policies.cmd text value. PG emits one of these strings.

pub const fn allows_with_check(self) -> bool

Whether WITH CHECK is valid for this command. PG rejects WITH CHECK on FOR SELECT and FOR DELETE policies.

pub const fn allows_using(self) -> bool

Whether USING is valid for this command. PG rejects USING on FOR INSERT policies (only WITH CHECK expression allowed for INSERT).

Trait Implementations

impl Clone for PolicyCommand

fn clone(&self) -> PolicyCommand

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PolicyCommand

impl Debug for PolicyCommand

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PolicyCommand

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for PolicyCommand

impl Hash for PolicyCommand

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 Ord for PolicyCommand

fn cmp(&self, other: &PolicyCommand) -> 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 PolicyCommand

fn eq(&self, other: &PolicyCommand) -> 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 PolicyCommand

fn partial_cmp(&self, other: &PolicyCommand) -> 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 PolicyCommand

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
