  )
}

Constructors

  max_age: Int,
)

FileSystem

</>

A swappable interface for file system operations.

pub type FileSystem {
  FileSystem(
    read_bits: fn(String) -> Result(BitArray, Nil),
    is_file: fn(String) -> Bool,
  )
}

Constructors

  read_bits: fn(String) -> Result(BitArray, Nil),
  is_file: fn(String) -> Bool,
)

    request.Req,
  ) -> response.Response(BitArray)
