Struct NeonBranchSource 

pub struct NeonBranchSource { /* private fields */ }

Available on crate feature neon only.

The overlay of the Neon branch an instance is bound to (its source config is a NeonBinding):

• Postgres: PGHOST (the direct host), PGUSER, PGDATABASE and PGPASSWORD, which the plan’s hosted-postgres reads, and DATABASE_URL (through the pooler) and DATABASE_URL_UNPOOLED for whatever reads those;
• object storage, when the binding has a credential: NEON_S3_ENDPOINT, NEON_S3_REGION, NEON_S3_ACCESS_KEY_ID and NEON_S3_SECRET_ACCESS_KEY;
• every bound function’s URL, in its variable (UNITYCATALOG_FUNCTION_URL). A function gone from the branch since binding is an error.

Neon’s credentials don’t expire, so the overlay never needs a refresh.

Implementations

impl NeonBranchSource

pub fn new(neon: Arc<dyn NeonControl>, secrets: SecretProviders) -> Self

The source, asking neon, with the storage credential’s secret resolved by secrets.

Trait Implementations

impl Source for NeonBranchSource

fn name(&self) -> &str

The name instances refer to it by.

fn overlay<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 SourceCtx, ) -> Pin<Box<dyn Future<Output = Result<Overlay, SourceError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The overlay for the instance ctx describes.

fn refresh<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, ctx: &'life1 SourceCtx, current: &'life2 Overlay, ) -> Pin<Box<dyn Future<Output = Result<Overlay, SourceError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

A fresh overlay once current has expired. The default asks again.
