Struct MigrationId 

pub struct MigrationId(/* private fields */);

A stable identifier for one domain-local schema migration attempt.

Implementations

impl MigrationId

pub const fn from_bytes(bytes: [u8; 32]) -> Self

Constructs an identifier from its exact protocol bytes.

pub const fn as_bytes(&self) -> &[u8; 32]

Returns the exact protocol bytes.

pub const fn to_bytes(self) -> [u8; 32]

Consumes this identifier and returns its exact protocol bytes.

Trait Implementations

impl AsRef<[u8]> for MigrationId

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

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for MigrationId

fn clone(&self) -> MigrationId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MigrationId

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

Formats the value using the given formatter.

impl<'bytes, Ctx> Decode<'bytes, Ctx> for MigrationId

fn decode( __d777: &mut Decoder<'bytes>, __ctx777: &mut Ctx, ) -> Result<MigrationId, Error>

Decode a value using the given Decoder.

fn nil() -> Option<Self>

If possible, return a nil value of Self.

impl Display for MigrationId

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

Formats the value using the given formatter.

impl<Ctx> Encode<Ctx> for MigrationId

fn encode<__W777>( &self, __e777: &mut Encoder<__W777>, __ctx777: &mut Ctx, ) -> Result<(), Error<__W777::Error>>

where __W777: Write,

Encode a value of this type using the given Encoder.

fn is_nil(&self) -> bool

Is this value of Self a nil value?

impl FromStr for MigrationId

type Err = FixedIdError

The associated error which can be returned from parsing.

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

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

impl Hash for MigrationId

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 MigrationId

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

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

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