pub struct Segment { /* private fields */ }
Expand description
A segment is a piece of the index.
Implementations
sourceimpl Segment
impl Segment
sourcepub fn meta(&self) -> &SegmentMeta
pub fn meta(&self) -> &SegmentMeta
Returns the segment meta-information
sourcepub fn relative_path(&self, component: SegmentComponent) -> PathBuf
pub fn relative_path(&self, component: SegmentComponent) -> PathBuf
Returns the relative path of a component of our segment.
It just joins the segment id with the extension associated to a segment component.
sourcepub fn open_read(
&self,
component: SegmentComponent
) -> Result<FileSlice, OpenReadError>
pub fn open_read(
&self,
component: SegmentComponent
) -> Result<FileSlice, OpenReadError>
Open one of the component file for a regular read.
sourcepub fn open_write(
&mut self,
component: SegmentComponent
) -> Result<WritePtr, OpenWriteError>
pub fn open_write(
&mut self,
component: SegmentComponent
) -> Result<WritePtr, OpenWriteError>
Open one of the component file for regular write.
