Struct DatabaseQuery 

pub struct DatabaseQuery {
    pub selector: Option<EventSelector>,
    pub range: Option<QueryRange>,
    pub direction: i32,
    pub limit: Option<u32>,
}

Complete database query with selector, range, direction and limits

Fields

selector: Option<EventSelector>

range: Option<QueryRange>

direction: i32

limit: Option<u32>

Implementations

impl DatabaseQuery

pub fn direction(&self) -> QueryDirection

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

pub fn set_direction(&mut self, value: QueryDirection)

Sets direction to the provided enum value.

pub fn limit(&self) -> u32

Returns the value of limit, or the default value if limit is unset.

Trait Implementations

impl Clone for DatabaseQuery

fn clone(&self) -> DatabaseQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DatabaseQuery

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

Formats the value using the given formatter.

impl Default for DatabaseQuery

fn default() -> Self

Returns the “default value” for a type.

impl Message for DatabaseQuery

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 DatabaseQuery

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