PropAMM SDK

Appearance

PriceLevelsRpcSource ​

Fetch-on-demand source for pAMM price levels: one titan_getPammPriceLevels 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.rpc.titanbuilder.xyz"),
));

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).
