Struct Reader 

pub struct Reader {
    pub source: Source,
    pub bytes_read: u64,
    pub decoded_events: usize,
    /* private fields */
}

A selected reader owns its ephemeral text/row files. Dropping or resetting it removes them.

Fields

source: Source

bytes_read: u64

decoded_events: usize

Implementations

impl Reader

pub fn new(source: Source) -> Self

pub fn commit(&mut self, width: usize)

pub fn id(&self) -> &SessionId

pub fn step( &mut self, width: usize, height: usize, position: Position, ) -> Window

Chunk scan and disk layout are bounded; the one-time typed decode of a completed record necessarily allocates its Event and formatted text, then releases both.

pub fn step_expanded( &mut self, width: usize, height: usize, position: Position, expanded: &BTreeSet<BlockId>, ) -> Window
