Struct DexClient 

pub struct DexClient { /* private fields */ }

Client for fetching DEX aggregator data.

Implementations

impl DexClient

pub fn new() -> Self

👎Deprecated since 0.8.0:

pass the transport: use DexClient::new_with_http

Creates a new DEX client with a transport built from the environment.

pub fn new_with_http(http: Arc<dyn HttpClient>) -> Self

Creates a new DEX client with a pre-built HTTP transport.

pub async fn get_token_price( &self, chain: &str, token_address: &str, ) -> Option<f64>

Fetches the USD price of a token by its address.

Returns None if the token is not found or has no price data.

pub async fn get_native_token_price(&self, chain: &str) -> Option<f64>

Fetches the native token price for a chain.

Uses well-known wrapped token addresses to determine the native token price.

pub async fn get_token_data( &self, chain: &str, token_address: &str, ) -> Result<DexTokenData>

Fetches token data from DexScreener.

Arguments

• chain - The blockchain name (e.g., “ethereum”, “bsc”)
• token_address - The token contract address

Returns

Returns aggregated token data from all DEX pairs.

pub async fn search_tokens( &self, query: &str, chain: Option<&str>, ) -> Result<Vec<TokenSearchResult>>

Searches for tokens by name or symbol.

Arguments

• query - The search query (token name or symbol)
• chain - Optional chain filter (e.g., “ethereum”, “bsc”)

Returns

Returns a vector of matching tokens sorted by liquidity.

pub async fn get_token_profiles(&self) -> Result<Vec<DiscoverToken>>

Fetches latest token profiles (featured tokens) from DexScreener.

pub async fn get_token_boosts(&self) -> Result<Vec<DiscoverToken>>

Fetches latest boosted tokens from DexScreener.

pub async fn get_token_boosts_top(&self) -> Result<Vec<DiscoverToken>>

Fetches top boosted tokens (most active boosts) from DexScreener.

pub fn estimate_7d_volume(volume_24h: f64) -> f64

Gets the 7-day volume by extrapolating from 24h data.

Note: DexScreener doesn’t provide 7d volume directly, so we estimate based on 24h volume.

Trait Implementations

impl Clone for DexClient

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for DexClient

fn default() -> Self

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Fetches comprehensive token data including pairs, volume, liquidity.

fn search_tokens<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query: &'life1 str, chain: Option<&'life2 str>, ) -> Pin<Box<dyn Future<Output = Result<Vec<TokenSearchResult>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Searches for tokens by query string with optional chain filter.
