Enum PgTable 

pub enum PgTable {
    Narinfo,
    Nar,
}

The two logical tables the cache tier keeps: narinfo text and NAR blobs.

A typed discriminant (never a stringly-typed table name at a call site) so the SQL for each table is chosen by an exhaustive match — a new table is a non-exhaustive-match compile error, and a typo’d table name cannot exist.

Variants

Narinfo

narinfo metadata, keyed by the 32-char store-path hash.

Nar

compressed NAR blobs, keyed by relative URL path (nar/<hash>.nar.xz).

Implementations

impl PgTable

pub const fn table_name(self) -> &'static str

The physical table name (for diagnostics / the real adapter’s DDL).

Trait Implementations

impl Clone for PgTable

fn clone(&self) -> PgTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for PgTable

impl Debug for PgTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for PgTable

impl PartialEq for PgTable

fn eq(&self, other: &PgTable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
