Struct WhereDocument 

pub struct WhereDocument {
    pub where_document: Option<WhereDocument>,
}

A WhereDocument clause for filtering metadata. A WhereDocument clause is a tree of WhereDocument clauses, where each node is exactly one of:

• A leaf node representing a $contains or $not_contains query directly.
• An branch node with a list of children and a way to combine them (AND or OR).

Fields

where_document: Option<WhereDocument>

Trait Implementations

impl Clone for WhereDocument

fn clone(&self) -> WhereDocument

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhereDocument

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

Formats the value using the given formatter.

impl Default for WhereDocument

fn default() -> Self

Returns the “default value” for a type.

impl Message for WhereDocument

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 WhereDocument

fn eq(&self, other: &WhereDocument) -> 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 TryFrom<WhereDocument> for Where

type Error = WhereConversionError

The type returned in the event of a conversion error.

fn try_from(proto_document: WhereDocument) -> Result<Self, Self::Error>

Performs the conversion.
