Struct RecordSchema 

pub struct RecordSchema<T> { /* private fields */ }

Fluent metadata descriptor for a Record.

This is the pure-Rust surface that #[derive(Record)] delegates to. The same record can be described by hand without the macro by implementing Record::record_schema with this builder; only the type-directed scan/bind methods then need to be provided.

Implementations

impl<T> RecordSchema<T>

pub fn new(table_name: &'static str) -> Self

Starts a record schema rooted at table_name.

pub fn schema(self, schema: impl Into<Option<&'static str>>) -> Self

Sets the optional table schema.

pub fn root(self, root: impl Into<Option<&'static str>>) -> Self

Sets the logical root alias used when scanning from a joined query.

pub fn reference(self, reference: ReferenceMeta) -> Self

Appends a single joined reference.

pub fn references(self, references: Vec<ReferenceMeta>) -> Self

Replaces the joined references.

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

Appends a single scan column name.

pub fn columns(self, columns: Vec<String>) -> Self

Replaces the scan column names.
