# `quote_exact_in`

This function calculates the result of a swap for a given amount of an exact input token.

**Function**

```rust theme={"system"}
pub fn quote_exact_in(
    pool: &VirtualPool,
    config: &PoolConfig,
    swap_base_for_quote: bool,
    current_timestamp: u64,
    current_slot: u64,
    in_amount: u64,
    has_referral: bool,
) -> Result<SwapResult2>
```

**Parameters**

* `pool`: A reference to the `VirtualPool` state.
* `config`: A reference to the `PoolConfig` for the pool.
* `swap_base_for_quote`: A boolean indicating the direction of the trade. `true` for swapping base token for quote token, `false` otherwise.
* `current_timestamp`: The current Solana cluster timestamp.
* `current_slot`: The current Solana cluster slot.
* `in_amount`: The amount of input tokens for the swap, excluding any transfer fees.
* `has_referral`: A boolean indicating if a referral fee should be considered.

**Returns**

It returns a `Result<SwapResult2>`, where `SwapResult2` contains detailed information about the outcome of the swap, such as the amount in, fees, and the next sqrt price of the token.

# `quote_exact_out`

This function calculates the result of a swap for a given amount of an exact output token.

**Function**

```rust theme={"system"}
pub fn quote_exact_out(
    pool: &VirtualPool,
    config: &PoolConfig,
    swap_base_for_quote: bool,
    current_timestamp: u64,
    current_slot: u64,
    out_amount: u64,
) -> Result<SwapResult2>
```

**Parameters**

* `pool`: A reference to the `VirtualPool` state.
* `config`: A reference to the `PoolConfig` for the pool.
* `swap_base_for_quote`: A boolean indicating the direction of the trade. `true` for swapping base token for quote token, `false` otherwise.
* `current_timestamp`: The current Solana cluster timestamp.
* `current_slot`: The current Solana cluster slot.
* `out_amount`: The amount of output tokens for the swap, excluding any transfer fees.

**Returns**

It returns a `Result<SwapResult2>`, where `SwapResult2` contains detailed information about the outcome of the swap, such as the amount in, fees, and the next sqrt price of the token.

# `quote_partial_fill`

This function calculates the result of a swap for a given amount of a partial input token. This is useful for trading terminals to not be hurt by the last swap overpaying.

**Function**

```rust theme={"system"}
pub fn quote_partial_fill(
    pool: &VirtualPool,
    config: &PoolConfig,
    swap_base_for_quote: bool,
    current_timestamp: u64,
    current_slot: u64,
    in_amount: u64,
    has_referral: bool,
) -> Result<SwapResult2>
```

**Parameters**

* `pool`: A reference to the `VirtualPool` state.
* `config`: A reference to the `PoolConfig` for the pool.
* `swap_base_for_quote`: A boolean indicating the direction of the trade. `true` for swapping base token for quote token, `false` otherwise.
* `current_timestamp`: The current Solana cluster timestamp.
* `current_slot`: The current Solana cluster slot.
* `in_amount`: The amount of input tokens for the swap, excluding any transfer fees.
* `has_referral`: A boolean indicating if a referral fee should be considered.

**Returns**

It returns a `Result<SwapResult2>`, where `SwapResult2` contains detailed information about the outcome of the swap, such as the amount in, fees, and the next sqrt price of the token.
