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

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,

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.

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 Serialize for StorageInstanceId

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

where __S: Serializer,
