Enum StorageInstanceId

pub enum StorageInstanceId {
    System(u64),
    User(u64),
}

Identifier of a storage instance.

Variants

System(u64)

A system storage instance.

User(u64)

A user storage instance.

Implementations

impl StorageInstanceId

pub fn system(id: u64) -> Option<Self>

Creates a new StorageInstanceId in the system namespace. The top 16 bits of id must be 0, because this ID is packed into 48 bits of mz_repr::GlobalId::IntrospectionSourceIndex.

pub fn user(id: u64) -> Option<Self>

Creates a new StorageInstanceId in the user namespace. The top 16 bits of id must be 0, because this ID is packed into 48 bits of mz_repr::GlobalId::IntrospectionSourceIndex.

fn new(id: u64, variant: fn(u64) -> Self) -> Option<Self>

pub fn inner_id(&self) -> u64

pub fn is_user(&self) -> bool

pub fn is_system(&self) -> bool

Trait Implementations

impl Arbitrary for StorageInstanceId

type Parameters = ()

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

type Strategy = BoxedStrategy<StorageInstanceId>

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

fn arbitrary_with((): 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 Clone for StorageInstanceId

fn clone(&self) -> StorageInstanceId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StorageInstanceId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StorageInstanceId

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StorageInstanceId

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

Formats the value using the given formatter.

impl FromStr for StorageInstanceId

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 StorageInstanceId

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 StorageInstanceId

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

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

fn partial_cmp(&self, other: &StorageInstanceId) -> 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 RustType<ProtoStorageInstanceId> for StorageInstanceId

fn into_proto(&self) -> ProtoStorageInstanceId

Convert a Self into a Proto value.

fn from_proto(proto: ProtoStorageInstanceId) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for StorageInstanceId

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
