Function: fetchPrice()

Get the latest price returned from the oracle.

Branches and code coverage (including function calls)

Intended branches

• If updated < block.timestamp, get the price from _fetchPrice and update the lastUpdated variable with current timestamp.

  Test coverage

• If updated >= block.timestamp, get the price by calling the function at signature sp.signature on the sp.collateral address.

  Test coverage

Negative behavior

• If updated >= block.timestamp, revert if the call to sp.collateral is unsuccessful.

  Test coverage

Function call analysis

• sp.collateral.call(abi.encode(sp.signature))

  • What is controllable? N/A.

  • If return value controllable, how is it used and how can it go wrong? Return values are not controllable.

  • What happens if it reverts, reenters, or does other unusual control flow? The entire function would revert if the external call reverts --- no reentrancy scenarios.
