Enum Capability 

pub enum Capability {
    S3,
    Pg,
}

A tier-agnostic thing a service needs, independent of who provides it.

Deliberately small: a capability earns a variant when a second implementation of it exists at a different tier, because that is the moment an app would otherwise have to fork. Pub/sub and secret-store are the obvious next candidates and are not here yet.

Variants

S3

An S3-compatible object store. local-s3-fs at dev, minio-container at sim, cloudflare-r2 at cloud/ha.

Pg

A PostgreSQL server reachable over pgwire. local-pg-dev at dev (R584-F1).

Note what this is not: the camp’s default store is service-owned libsql, embedded in the service process, and those services never touch this capability. pg is for non-rust services and rust services that specifically want the wire protocol.

Implementations

impl Capability

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

The key this capability is declared under in [drivers.<key>].

pub fn for_component_kind(kind: &str) -> &'static [Capability]

Capabilities implied by a component’s kind.

kind is a free-form string in service.toml, so an unknown kind maps to no capabilities rather than an error — a component kind this build doesn’t know about is a forward-compat case, not a misconfiguration.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Capability

impl Debug for Capability

impl Ord for Capability

fn cmp(&self, other: &Capability) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
