Struct brontes_pricing::AllPairGraph

source · 
pub struct AllPairGraph { /* private fields */ }
Expand description

AllPairGraph Represents the interconnected network of token pairs in decentralized exchanges (DEXs), crucial for the BrontesBatchPricer system’s ability to analyze and calculate token prices.

AllPairGraph forms a graph structure where each node represents a token and each edge a connection between tokens, typically through a liquidity pool. This structure allows for efficient navigation and identification of trading routes, and for determining the relative prices of tokens.

The graph is dynamic, adapting to the ever-changing landscape of the DEX environment. It incorporates new tokens and pools as they emerge, and adjusts or removes connections when changes in liquidity or pool validity occur. This ensures that the representation of the token network remains accurate and current.

The ability to assess the number of connections a token has, as well as to identify paths for trading between any two tokens, is fundamental to the system. It enables the evaluation of liquidity and trading opportunities. The graph also provides the capability to exclude certain paths or connections, catering to scenarios where specific routes might be temporarily infeasible or less desirable.
