Struct tendermint::abci::request::Query

pub struct Query {
    pub data: Bytes,
    pub path: String,
    pub height: Height,
    pub prove: bool,
}

Queries for data from the application at current or past height.

ABCI documentation

Fields

data: Bytes

Raw query bytes.

Can be used with or in lieu of path.

path: String

Path of the request, like an HTTP GET path.

Can be used with or in lieu of data.

Applications MUST interpret /store as a query by key on the underlying store. The key SHOULD be specified in the Data field. Applications SHOULD allow queries over specific types like /accounts/... or /votes/....

height: Height

The block height for which the query should be executed.

The default 0 returns data for the latest committed block. Note that this is the height of the block containing the application’s Merkle root hash, which represents the state as it was after committing the block at height - 1.

prove: bool

Whether to return a Merkle proof with the response, if possible.

Trait Implementations

impl Clone for Query

fn clone(&self) -> Query

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Query

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

Formats the value using the given formatter.

impl From<Query> for RequestQuery

fn from(query: Query) -> Self

Performs the conversion.

impl PartialEq<Query> for Query

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

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

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

This method tests for !=.

impl Protobuf<RequestQuery> for Query

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

Encode into a buffer in Protobuf format.

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

Encode with a length-delimiter to a buffer in Protobuf format.

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

Constructor that attempts to decode an instance from a buffer.

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

fn encoded_len(&self) -> usize

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

fn encode_vec(&self) -> Result<Vec<u8, Global>, Error>

Encodes into a Protobuf-encoded Vec<u8>.

fn decode_vec(v: &[u8]) -> Result<Self, Error>

Constructor that attempts to decode a Protobuf-encoded instance from a Vec<u8> (or equivalent).

fn encode_length_delimited_vec(&self) -> Result<Vec<u8, Global>, Error>

Encode with a length-delimiter to a Vec<u8> Protobuf-encoded message.

fn decode_length_delimited_vec(v: &[u8]) -> Result<Self, Error>

Constructor that attempts to decode a Protobuf-encoded instance with a length-delimiter from a Vec<u8> or equivalent.

impl TryFrom<RequestQuery> for Query

type Error = Error

The type returned in the event of a conversion error.

fn try_from(query: RequestQuery) -> Result<Self, Self::Error>
