Enum Resource 

pub enum Resource {
    Database,
    Schema(String),
    Table {
        schema: Option<String>,
        table: String,
    },
    Function {
        schema: Option<String>,
        name: String,
    },
}

Object the grant covers. Schemas and tables form a hierarchy: a grant on Schema("public") implicitly covers every table in public.

Variants

Database

Cluster-wide (PG: ON DATABASE).

Schema(String)

All objects within a schema.

Table

A specific table (optionally schema-qualified).

Fields

schema: Option<String>

table: String

Function

A function (UDF / aggregate).

Fields

schema: Option<String>

name: String

Implementations

impl Resource

pub fn table_from_name(name: &str) -> Resource

Construct a Table resource from a possibly dotted name. "public.users" → Table { schema: Some("public"), table: "users" }. "users" → Table { schema: None, table: "users" }.

pub fn covers(&self, requested: &Resource) -> bool

Does self (a grant resource) cover requested? Database covers everything; Schema(s) covers any Table { schema: Some(s), .. }; everything else requires equality.

Trait Implementations

impl Clone for Resource

fn clone(&self) -> Resource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl Hash for Resource

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 Resource

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

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

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