Struct TableAccessPolicy 

pub struct TableAccessPolicy {
    pub operations: BTreeSet<AccessOperation>,
    pub denied_operations: BTreeSet<AccessOperation>,
    pub read_columns: ColumnRule,
    pub write_columns: ColumnRule,
    pub returning_columns: ColumnRule,
    pub require_any_role: BTreeSet<String>,
    pub require_scopes: BTreeSet<String>,
}

Access rule for one table.

Fields

operations: BTreeSet<AccessOperation>

Allowed operations.

denied_operations: BTreeSet<AccessOperation>

Explicitly denied operations.

read_columns: ColumnRule

Read projection rule.

write_columns: ColumnRule

Write payload rule.

returning_columns: ColumnRule

RETURNING projection rule. Enforced together with read_columns.

require_any_role: BTreeSet<String>

At least one of these roles is required. Empty means no role gate.

require_scopes: BTreeSet<String>

All listed scopes are required. Empty means no scope gate.

Implementations

impl TableAccessPolicy

pub fn new() -> Self

Empty table policy: no operations allowed until added.

pub fn allow_operations<I>(self, operations: I) -> Self

where I: IntoIterator<Item = AccessOperation>,

Allow the listed operations.

pub fn deny_operations<I>(self, operations: I) -> Self

where I: IntoIterator<Item = AccessOperation>,

Deny the listed operations even if otherwise allowed.

pub fn read_columns(self, rule: ColumnRule) -> Self

Restrict read projection columns.

pub fn write_columns(self, rule: ColumnRule) -> Self

Restrict write payload columns.

pub fn returning_columns(self, rule: ColumnRule) -> Self

Restrict RETURNING columns.

pub fn require_any_role<I, S>(self, roles: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require at least one role.

pub fn require_scopes<I, S>(self, scopes: I) -> Self

where I: IntoIterator<Item = S>, S: Into<String>,

Require all scopes.

Trait Implementations

impl Clone for TableAccessPolicy

fn clone(&self) -> TableAccessPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableAccessPolicy

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

Formats the value using the given formatter.

impl Default for TableAccessPolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TableAccessPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for TableAccessPolicy

impl PartialEq for TableAccessPolicy

fn eq(&self, other: &TableAccessPolicy) -> 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 Serialize for TableAccessPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
