Expand description

Find cell data by OutPoint

Retrieves the data contained in a cell identified by the specified OutPoint. The cell’s data is written to the provided buffer.

§Arguments

  • buf - A mutable buffer to receive the cell’s data
  • out_point - The serialized OutPoint identifying the cell whose data to retrieve

§Returns

  • Ok(usize) - The actual length of the cell data written to the buffer
  • Err(SysError) - A system error if the operation fails

§Errors

Returns SysError::LengthNotEnough if the buffer is too small to hold the data Returns SysError::IndexOutOfBound if the OutPoint is invalid Returns SysError::ItemMissing if the cell cannot be found
