Implementations

impl TableChange

pub fn new<T: AsRef<str>, K: AsRef<str>>( entity: T, pk: K, ordinal: u64, operation: Operation ) -> TableChange

pub fn new_composite<T: AsRef<str>>( entity: T, keys: HashMap<String, String>, ordinal: u64, operation: Operation ) -> TableChange

pub fn change<N: AsRef<str>, T: ToField>( &mut self, name: N, change: T ) -> &mut TableChange

impl TableChange

pub fn operation(&self) -> Operation

Returns the enum value of operation, or the default if the field is set to an invalid enum value.

pub fn set_operation(&mut self, value: Operation)

Sets operation to the provided enum value.

Trait Implementations

impl Clone for TableChange

fn clone(&self) -> TableChange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TableChange

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

Formats the value using the given formatter.

impl Default for TableChange

fn default() -> Self

Returns the “default value” for a type.

impl Message for TableChange

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode<B>(&self, buf: &mut B) -> Result<(), EncodeError>where B: BufMut, Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8, Global>where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited<B>(&self, buf: &mut B) -> Result<(), EncodeError>where B: BufMut, Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8, Global>where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode<B>(buf: B) -> Result<Self, DecodeError>where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>where B: Buf, Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq<TableChange> for TableChange

fn eq(&self, other: &TableChange) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
