Struct Table 

pub struct Table { /* private fields */ }

The committed table directory.

Implementations

impl Table

pub fn name(&self) -> &str

The SQL table name held by this snapshot.

pub fn fields(&self) -> &[Field]

Columns in their SQL order.

pub fn rows(&self) -> usize

Committed row count.

pub fn stripes(&self) -> &[Stripe]

Independently readable stripes.

pub fn clustering(&self) -> Option<&Clustering>

The order the rows are meant to be stored in, if this table was declared with one.

pub fn generation(&self) -> u64

The generation every section of this table is judged against.

See the field. A caller deciding whether to read a section asks Section::usable with this.

pub fn sections(&self) -> &[Section]

Every graph section this table names, including the kinds this build does not know.

Including them is the point. A caller that wants only the ones it can use asks Section::usable, and a caller rewriting the directory carries the rest through, so a file opened by an older build and written again does not silently lose a section that build had no name for.
