Module schema 

Core schema traits for compile-time Arrow typing.

Structs

FieldMeta

Simple compile-time column metadata passed to visitors.

Traits

AppendStruct

Trait implemented by #[derive(Record)] structs to append their fields into a StructBuilder. Used by row-based APIs to handle nested struct fields.

AppendStructRef

Trait implemented by #[derive(Record)] structs to append their fields into a StructBuilder from a borrowed reference. This enables container builders (e.g., lists of structs) to append child values without taking ownership of the struct.

BuildRows

Row-based building interface: construct typed column builders, append owned rows, and finish into typed arrays.

ColAt

Per-column metadata for a record at index I.

ColumnVisitor

A visitor invoked at compile time for each column of a Record.

ForEachCol

Trait emitted by derive/macro to enable for_each_col expansion.

FromRecordBatch

Trait for creating zero-copy views over a RecordBatch.

IntoRecordBatch

Trait implemented by derive-generated arrays to assemble a RecordBatch.

Record

A record (row) with a fixed, compile-time number of columns.

RowBuilder

Trait implemented by derive-generated builders to append rows of Row and finish into a typed arrays struct.

SchemaMeta

Arrow runtime schema metadata for a top-level Record.

StructMeta

Metadata and builder utilities for nested Struct fields.

StructView

Trait for creating a view from a StructArray at a specific index.

ViewResultIteratorExt

Extension trait providing convenience methods for iterators over Result<T, ViewAccessError>.
