PropAMM SDK

Appearance

PriceLevelsRpcSource ​

Fetch-on-demand source for pAMM price levels: one titan_getPammBooks call per get_price_levels. Also exposes the quote helpers directly. Simplest for sporadic use.

Usage ​

rust
use propamm::prices::{PriceLevels, PriceLevelsRpcSource};
use std::sync::Arc;

// custom endpoint — snapshot and quotes both use it
let prices = PriceLevels::with_source(Arc::new(
    PriceLevelsRpcSource::new("https://us.data.titanbuilder.xyz/data"),
));

Constructors ​

PriceLevelsRpcSource::new() ​

rust
pub fn new(url: impl Into<String>) -> Self

PriceLevelsRpcSource::default() ​

rust
impl Default for PriceLevelsRpcSource

Equivalent to new(DEFAULT_PRICE_LEVELS_RPC_URL).

PriceLevelsRpcSource::with_decimals() ​

rust
pub fn with_decimals(self, decimals: HashMap<Address, u8>) -> Self

Decimals of tokens missing from TOKEN_DECIMALS, by token address (an entry also overrides the built-in value). Titan's v2 feed sends amounts in human units, so a book quoting a token without known decimals is skipped.

Methods ​

Implements PriceLevelsSource.

get_price_levels() ​

rust
async fn get_price_levels(&self) -> Result<Arc<PriceLevelsSnapshot>>

Fresh snapshot via titan_getPammBooks. Errors on HTTP or JSON-RPC failure.

get_quote() ​

rust
pub async fn get_quote(
    &self,
    token_in: Address,
    token_out: Address,
    amount_in: U256,
) -> Result<TitanQuote>

get_quote_venue() ​

rust
pub async fn get_quote_venue(
    &self,
    venue: Address,
    token_in: Address,
    token_out: Address,
    amount_in: U256,
) -> Result<TitanQuote>
