Enum Target 

pub enum Target {
    Docs,
    Blocks,
    Nodes,
    Links,
    Revisions,
}

The five root collections (spec/surface §1.1): the four live row kinds and, since 4.7, revisions — the history target, one row per revision of the repository’s documents (the revisions × commits join). The reference splits the name in two (Target, the four kinds its planner pushes down and its unknown-names pass first keyed by; Kind/Root, all five); here one enum tags every row, and the planner declines the fifth (crate::planner::root_target is five-wide, compile plans four).

Implementations

impl Target

pub fn as_str(self) -> &'static str

The root name: docs | blocks | nodes | links | revisions.

pub fn parse(s: &str) -> Option<Self>

The target a root name denotes, if any.

pub fn noun(self) -> &'static str

The plural noun of the kind’s rows, as the root-row messages spell it (crate::query: “the repository’s documents”).
