Struct Parameter 

pub struct Parameter {
    pub key: String,
    pub value: String,
    /* private fields */
}

A single query parameter for a parameterized Dune query.

The parameter name must match the name defined in the query on Dune (e.g. in the query editor). Use the constructors Parameter::text, Parameter::number, Parameter::date, and Parameter::list to build parameters of the correct type.

Example

use duners::Parameter;
use chrono::Utc;

let params = vec![
    Parameter::text("WalletAddress", "0x1234..."),
    Parameter::number("MinAmount", "100"),
    Parameter::list("Token", "ETH"),
    Parameter::date("StartDate", Utc::now()),
];

Fields

key: String

Parameter name (must match the query’s parameter name on Dune).

value: String

String value sent to the API.

Implementations

impl Parameter

pub fn date(name: &str, value: DateTime<Utc>) -> Self

Builds a date parameter. The value is sent as YYYY-MM-DD HH:MM:SS.

pub fn text(name: &str, value: &str) -> Self

Builds a text parameter (e.g. addresses, hashes, plain strings).

pub fn number(name: &str, value: &str) -> Self

Builds a number parameter. Pass the value as a string (e.g. "42" or "3.14").

pub fn list(name: &str, value: &str) -> Self

Builds a list/enum parameter (dropdown-style; value must match one of the query’s options).

Trait Implementations

impl Debug for Parameter

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

Formats the value using the given formatter.

impl PartialEq for Parameter

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