Module schema 

Engine-agnostic schema types.

This module provides types that describe protocol field schemas without depending on any specific SQL engine (Arrow, DuckDB, etc.).

Example

use pcapsql_core::schema::{DataKind, FieldDescriptor};

// Define a protocol's schema
let fields = vec![
    FieldDescriptor::frame_number(),
    FieldDescriptor::new("version", DataKind::UInt8),
    FieldDescriptor::nullable("payload", DataKind::Binary),
];

Structs

FieldDescriptor

Enums

Type Aliases
