Struct RestApi 

pub struct RestApi { /* private fields */ }

Implementations

impl RestApi

pub fn new(base_url: impl Into<String>) -> Self

Create a new REST API pointing at base_url. Uses the legacy default response shape ({ "data": [...] }). For other shapes (bare array, wrapped-by-table-name) use RestApi::builder.

pub fn builder(base_url: impl Into<String>) -> RestApiBuilder

Start configuring a RestApi via the builder.

pub fn with_auth(self, auth: impl Into<String>) -> Self

Set the Authorization header value (e.g. “Bearer <token>”). Provided for backwards compatibility — prefer RestApi::builder(...).auth(...).

impl RestApi

pub fn vista_factory(&self) -> RestApiVistaFactory

Return a Vista factory bound to this REST API data source.

Trait Implementations

impl Clone for RestApi

fn clone(&self) -> RestApi

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl DataSource for RestApi

impl Debug for RestApi

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

Formats the value using the given formatter.

impl ExprDataSource<Value> for RestApi

async fn execute(&self, expr: &Expression<CborValue>) -> Result<CborValue>

fn defer(&self, expr: Expression<CborValue>) -> DeferredFn<CborValue>

fn associate<R>( &self, expr: Expression<T>, ) -> AssociatedExpression<'_, Self, T, R>

where Self: Sized,

Create an associated expression with type-safe return type

impl TableSource for RestApi

fn eq_condition(field: &str, value: &str) -> Result<Self::Condition>

Build a stringy field == value eq-condition. Stringy callers (the model-driven CLI) only have text on hand; values arrive as String and become CBOR text scalars here. The peeling code in condition_to_query_param renders all scalar variants the same way so the URL still reads correctly.

fn eq_value_condition( &self, field: &str, value: Self::Value, ) -> Result<Self::Condition>

Typed-value sibling of eq_condition. Used by Reference::resolve_from_row to push a row-derived join value onto a child table without a string round-trip.

fn related_in_condition<SourceE: Entity<Self::Value> + 'static>( &self, target_field: &str, source_table: &Table<Self, SourceE>, source_column: &str, ) -> Self::Condition

where Self: Sized,

Build a child condition for with_many / with_one traversal.

REST APIs can’t run subqueries, so this resolves on two paths:

• Sync peek — if the parent already carries an eq-condition on source_column, we re-key its value onto target_field and we’re done. Covers the common with_many case where source_column is the parent’s id field (narrowed via id=N or [N]).
• Deferred read — otherwise (the with_one case, where source_column is a foreign-key field that lives in the parent’s record, not its conditions), we wrap the resolution in a DeferredFn that fetches the parent at request time and pulls the field out of the row. fetch_records resolves deferreds before peeling conditions into query params.

type Column<Type> = Column<Type> where Type: ColumnType

type AnyType = Value

type Value = Value

type Id = String

type Condition = Expression<<RestApi as TableSource>::Value>

The condition type stored by Table. SQL/SurrealDB backends use Expression<Self::Value>; document-oriented backends like MongoDB can use a native filter type (e.g. bson::Document).

type Source = String

How this backend names its source. Most backends use String; SQL/SurrealDB backends use SelectSource<Self::Select> so a table can be sourced from an arbitrary sub-SELECT. See crate::source.
