```rust
/// Collect reward for a given position.
///
/// # Arguments
///
/// _ config - A reference to the GlobalConfig object.
/// _ pool - A mutable reference to the Pool object.
/// _ position_nft - A reference to the Position object for which to collect rewards.
/// _ vault - A mutable reference to the RewarderGlobalVault object.
/// _ recalculate - A boolean indicating whether to recalculate the reward rate.
/// _ clock - A reference to the Clock object used to determine the current time.
///
/// # Generic Type Parameters
///
/// _ CoinTypeA - The type of the first coin in the pool.
/// _ CoinTypeB - The type of the second coin in the pool.
/// \* CoinTypeC - The type of the reward coin.

## Example

        config,
        pool,
        position_nft,
        vault,

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cetus-1.gitbook.io/cetus-developer-docs/developer/via-clmm-contract/features-available/collect-reward.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
