Struct ListSchemas 

pub struct ListSchemas { /* private fields */ }

List all schemas in the current database.

Examples

use ironflow_ops_postgres::schema::schemas::ListSchemas;
use ironflow_core::operation::Operation;

let op = ListSchemas::new(pool);
assert_eq!(op.kind(), "postgres");

Implementations

impl ListSchemas

pub fn new(pool: PgPool) -> Self

Create a new list-schemas operation.

pub async fn run( &self, _ctx: &OperationContext, ) -> Result<ListSchemasOutput, OperationError>

Execute and return a typed result.

Errors

Returns OperationError::External on connection errors.

Trait Implementations

impl Operation for ListSchemas

fn kind(&self) -> &str

A short, lowercase identifier for this operation type.

fn execute<'life0, 'life1, 'async_trait>( &'life0 self, ctx: &'life1 OperationContext, ) -> Pin<Box<dyn Future<Output = Result<Value, OperationError>> + Send + 'async_trait>>

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

Execute the operation and return the result as JSON.

fn input(&self) -> Option<Value>

Optional JSON representation of the operation input, stored in the step’s input column for observability.

impl TypedOperation for ListSchemas

type Output = ListSchemasOutput

The concrete output type that Operation::execute produces.
