Struct PgGraphMemoryBuilder 

pub struct PgGraphMemoryBuilder<N, E> { /* private fields */ }

Fluent builder for PgGraphMemory. Use PgGraphMemory::builder.

Implementations

impl<N, E> PgGraphMemoryBuilder<N, E>

pub fn new() -> Self

Empty builder.

pub fn with_connection_string(self, url: impl Into<String>) -> Self

Postgres connection string. Mutually exclusive with Self::with_pool — the builder rejects construction if both are set.

pub fn with_pool(self, pool: Arc<PgPool>) -> Self

Reuse an existing pool — useful when the operator already manages a PgPool for other persistence layers and wants PgGraphMemory to share it.

pub fn with_nodes_table(self, name: impl Into<String>) -> Self

Override the nodes table name (default graph_nodes).

pub fn with_edges_table(self, name: impl Into<String>) -> Self

Override the edges table name (default graph_edges).

pub const fn with_auto_migrate(self, on: bool) -> Self

Toggle the idempotent schema bootstrap. Default true; set to false when the schema is owned externally.

pub async fn build(self) -> PgGraphMemoryResult<PgGraphMemory<N, E>>

Open the pool (if needed), run the migration (if enabled), and return the configured backend.

impl<N, E> Default for PgGraphMemoryBuilder<N, E>

fn default() -> Self

Returns the “default value” for a type.
