[−][src]Struct rosbag::msg_iter::ChunkRecordsIterator
Iterator which iterates over records stored in the
Chunk
.
Methods
impl<'a> ChunkRecordsIterator<'a>
[src]
pub fn seek(&mut self, offset: u32) -> Result<()>
[src]
Seek to an offset, in bytes from the beggining of an internall chunk buffer.
Offset values can be taken from IndexData
records which follow
Chunk
used for iterator initialization. Be careful though, as
incorrect offset value will lead to errors.
