Implementations

impl IndexElem

pub fn to_ref(&self) -> NodeRef<'_>

pub fn to_mut(&mut self) -> NodeMut

impl IndexElem

pub fn ordering(&self) -> SortByDir

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

pub fn set_ordering(&mut self, value: SortByDir)

Sets ordering to the provided enum value.

pub fn nulls_ordering(&self) -> SortByNulls

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

pub fn set_nulls_ordering(&mut self, value: SortByNulls)

Sets nulls_ordering to the provided enum value.

Trait Implementations

impl Clone for IndexElem

fn clone(&self) -> IndexElem

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IndexElem

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

Formats the value using the given formatter.

impl Default for IndexElem

fn default() -> Self

Returns the “default value” for a type.

impl Message for IndexElem

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(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

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

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

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

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

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

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

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

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

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

impl PartialEq for IndexElem

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