Crate wp_solana_core 

wp-solana-core — cross-protocol shared crate for waterpump-solana.

Contains shared code that every protocol SDK (Raydium, Meteora, Orca) needs:

• token/ — token account planning types, state types, transfer-fee helper
• metadata — decode_mint_info / read_mint_decimals mint-account byte-decoders shared by every protocol fetch layer
• plan_error — PlanError, FetchError, OrchestrateError (FCIS error types)
• constants — Solana system program addresses (protocol-agnostic)

Layering note

Core exposes synchronous compatibility helpers and shared error/types. Token account state/planning primitives are re-exported from solana-token-toolkit.

Re-exports

pub use metadata::decode_mint_info;

pub use metadata::read_mint_decimals;

pub use plan_error::FetchError;

pub use plan_error::OrchestrateError;

pub use plan_error::PlanError;

pub use token::account_planner::TokenAccountInstructions;

pub use token::account_planner::TokenAccountStrategy;

pub use token::get_current_transfer_fee;

Modules

constants

Protocol-agnostic Solana system program constants.

metadata

Mint-account decoding helpers shared by every protocol’s fetch layer.

Structs

MintAndAta
