Enum Action 

pub enum Action {
    Select,
    Insert,
    Update,
    Delete,
    Truncate,
    References,
    Execute,
    Usage,
    All,
}

SQL action covered by a grant. Mirrors PG’s privilege vocabulary.

Variants

Select

SELECT on a table / view.

Insert

INSERT on a table.

Update

UPDATE on a table.

Delete

DELETE on a table.

Truncate

TRUNCATE TABLE.

References

REFERENCES (FK target privilege).

Execute

EXECUTE on a function.

Usage

USAGE on a schema or sequence.

All

All privileges (PG ALL [PRIVILEGES]).

Implementations

impl Action

pub fn from_keyword(kw: &str) -> Option<Action>

Parse a privilege keyword (case-insensitive). Returns None for unrecognised tokens so the parser can produce a precise error.

pub fn as_str(self) -> &'static str

Trait Implementations

impl Clone for Action

fn clone(&self) -> Action

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Action

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

Formats the value using the given formatter.

impl Hash for Action

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

where __H: Hasher,

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 Action

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

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

fn partial_cmp(&self, other: &Action) -> 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.
