Module base::file_traits

Traits

• FileAllocate
  A trait for allocating disk space in a sparse file. This is equivalent to fallocate() with no special flags.
• FileGetLen
  A trait for getting the size of a file. This is equivalent to File’s metadata().len() method, but wrapped in a trait so that it can be implemented for other types.
• FileReadWriteAtVolatile
  A trait similar to the unix ReadExt and WriteExt traits, but for volatile memory.
• FileReadWriteVolatile
  A trait similar to Read and Write, but uses volatile memory as buffers.
• FileSetLen
  A trait for setting the size of a file. This is equivalent to File’s set_len method, but wrapped in a trait so that it can be implemented for other types.
• FileSync
  A trait for flushing the contents of a file to disk. This is equivalent to File’s sync_all and sync_data methods, but wrapped in a trait so that it can be implemented for other types.
