Struct QueryBuilder 

pub struct QueryBuilder<T> { /* private fields */ }

Builder returned by the public and private client. All methods are optional but the builder must be consumed with one of the terminal methods. Methods belonging to this struct can be chained and calling the same method more than once will overwrite the previously set value.

Implementations

impl<'a, T: Params<'a>> QueryBuilder<T>

pub async fn text(self) -> Result<String>

pub async fn json<J: DeserializeOwned>(self) -> Result<J>

General terminal method

Example

let products = client
    .get_products()
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&products).unwrap());

impl<'a, T: Params<'a> + ProductID<'a>> QueryBuilder<T>

pub fn product_id(self, value: &'a str) -> Self

Sets product id

Example

let response = client.cancel_all()
    .product_id("BTC-USD")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

impl<'a, T: Params<'a> + Book<'a>> QueryBuilder<T>

pub fn level(self, value: i32) -> Self

Sets level for order book data. Max level is 3.

Example

let order_book = client.get_product_order_book("BTC-USD")
    .level(3)
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&order_book).unwrap());

impl<'a, T: Params<'a> + Paginate<'a> + Send + Unpin + 'a> QueryBuilder<T>

pub fn limit(self, value: i32) -> Self

Sets limit for the ammount of pages each request will return. Max number of pages is 100.

Example

let mut pages = client.get_trades("BTC-USD")
    .limit(10)
    .after(7102310) // after or before but not both
    .paginate::<serde_json::Value>()?; // or .json::<serde_json::Value>().await? for a single request

while let Some(json) = pages.try_next().await? {
    println!("{}", serde_json::to_string_pretty(&json).unwrap());
    tokio::time::sleep(core::time::Duration::new(1, 0)).await;
}

pub fn before(self, value: i32) -> Self

Gets newer page from the trade id specified.

pub fn after(self, value: i32) -> Self

Gets older page from the trade id specified.

pub fn paginate<J: DeserializeOwned>(self) -> Result<Pages<'a, J>>

Terminal method returning a stream of json pages

impl<'a, T: Params<'a> + Candle<'a>> QueryBuilder<T>

pub fn range<Tz: TimeZone>(self, start: DateTime<Tz>, end: DateTime<Tz>) -> Self

where Tz::Offset: Display,

Sets start and end time for historic rates. If the range results in more than 300 candles, the request will be rejected.

Example

let end = chrono::offset::Utc::now();
let start = end - chrono::Duration::hours(5);

let rates = client
    .get_historic_rates("BTC-USD", 3600)
    .range(start, end)
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&rates).unwrap());

impl<'a, T: Params<'a> + ClientOID<'a>> QueryBuilder<T>

pub fn client_oid(self, value: &'a str) -> Self

Sets uuid as part of this order

Example

let response = client.place_market_order("BTC-USD", "buy", QTY::Size(10.00))
    .client_oid("<client_oid>")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

impl<'a, T: Params<'a> + Limit<'a>> QueryBuilder<T>

pub fn stp(self, value: &'a str) -> Self

Sets Self-trade prevention flag.

Example

let response = client
    .place_limit_order("BTC-USD", "sell", 7000.00, 10.00)
    .stp("dc")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

pub fn stop_price(self, value: f64) -> Self

Turns sell limit order into a stop loss or a stop entry for a buy limit order.

Example

let response = client
    .place_limit_order("BTC-USD", "sell", 7000.00, 10.00)
    .stop_price(7010.00)
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

pub fn time_in_force(self, value: &'a str) -> Self

Sets time in force policy. (default is GTC) Valid inputs are: “GTC”, “GTT”, “IOC”, “FOK”.

Example

let response = client
    .place_limit_order("BTC-USD", "sell", 7000.00, 10.00)
    .time_in_force("GTT")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

pub fn cancel_after(self, value: &'a str) -> Self

Sets time before order is cancelled Valid inputs are: “min”, “hour”, “day”.

Example

let response = client
    .place_limit_order("BTC-USD", "sell", 7000.00, 10.00)
    .cancel_after("min")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

pub fn post_only(self, value: bool) -> Self

The post-only flag indicates that the order should only make liquidity. If any part of the order results in taking liquidity, the order will be rejected and no part of it will execute. Invalid when time_in_force is IOC or FOK.

Example

let response = client
    .place_limit_order("BTC-USD", "sell", 7000.00, 10.00)
    .post_only(true)
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&response).unwrap());

impl<'a, T: Params<'a> + Report<'a>> QueryBuilder<T>

pub fn format(self, value: &'a str) -> Self

Sets format of output report. Valid inputs are “pdf” or “csv” (defualt is pdf)

Example

use chrono::{ TimeZone, Utc };
 
let start_date = Utc.ymd(2018, 8, 10).and_hms(0, 0, 0);
let end_date = Utc.ymd(2018, 8, 28).and_hms(0, 0, 0);

let rates = client.create_report(start_date, end_date, RPT::Fills { product_id: "BTC-USD" })
    .format("pdf")
    .email("<email>")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&rates).unwrap());

pub fn email(self, value: &'a str) -> Self

Sets to send report to. Valid inputs are “pdf” or “csv” (defualt is pdf)

Example

use chrono::{ TimeZone, Utc };
 
let start_date = Utc.ymd(2018, 8, 10).and_hms(0, 0, 0);
let end_date = Utc.ymd(2018, 8, 28).and_hms(0, 0, 0);

let rates = client
    .create_report(start_date, end_date, RPT::Fills { product_id: "BTC-USD" })
    .email("<email>")
    .json::<serde_json::Value>()
    .await?;
 
println!("{}", serde_json::to_string_pretty(&rates).unwrap());
