Struct MzAclItem

pub struct MzAclItem {
    pub grantee: RoleId,
    pub grantor: RoleId,
    pub acl_mode: AclMode,
}

A list of privileges granted to a role in Materialize.

This is modelled after the AclItem type in PostgreSQL, but the OIDs are replaced with RoleIds because we don’t use OID as persistent identifiers for roles.

See: https://github.com/postgres/postgres/blob/7f5b19817eaf38e70ad1153db4e644ee9456853e/src/include/utils/acl.h#L48-L59

Fields

grantee: RoleId

Role that this item grants privileges to.

grantor: RoleId

Grantor of privileges.

acl_mode: AclMode

Privileges bit flag.

Trait Implementations

impl Arbitrary for MzAclItem

type Parameters = (<RoleId as Arbitrary>::Parameters, <RoleId as Arbitrary>::Parameters, <AclMode as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<RoleId as Arbitrary>::Strategy, <RoleId as Arbitrary>::Strategy, <AclMode as Arbitrary>::Strategy), fn((RoleId, RoleId, AclMode)) -> MzAclItem>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl AsColumnType for MzAclItem

fn as_column_type() -> SqlColumnType

The SQL column type of this Rust type

impl Clone for MzAclItem

fn clone(&self) -> MzAclItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Columnation for MzAclItem

type InnerRegion = CopyRegion<MzAclItem>

The type of region capable of absorbing allocations owned by the Self type. Note: not allocations of Self, but of the things that it owns.

impl<'a, E> DatumType<'a, E> for MzAclItem

fn nullable() -> bool

fn fallible() -> bool

Whether this Rust type can represent errors

fn try_from_result( res: Result<Datum<'a>, E>, ) -> Result<Self, Result<Datum<'a>, E>>

Try to convert a Result whose Ok variant is a Datum into this native Rust type (Self). If it fails the error variant will contain the original result.

fn into_result(self, _temp_storage: &'a RowArena) -> Result<Datum<'a>, E>

Convert this Rust type into a Result containing a Datum, or an error

impl Debug for MzAclItem

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

impl<'de> Deserialize<'de> for MzAclItem

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MzAclItem

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

Formats the value using the given formatter.

const SIZE: usize = 32usize

Number of bytes the encoded format requires.

fn as_bytes(&self) -> &[u8]

Returns the encoded bytes as a slice.

fn from_bytes(val: &[u8]) -> Result<Self, String>

where Self: Sized,

Create an instance of self from a slice.

fn from_value(value: MzAclItem) -> Self

Encode a type of T into this format.

fn into_value(self) -> MzAclItem

impl<'a> From<MzAclItem> for Datum<'a>

fn from(mz_acl_item: MzAclItem) -> Self

Converts to this type from the input type.

impl FromStr for MzAclItem

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for MzAclItem

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 MzAclItem

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

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

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

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

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

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.
