Function resolve_schema 

pub fn resolve_schema(
    table: &str,
    method: &str,
    headers: Option<&HashMap<String, String>>,
) -> Result<ResolvedTable, Error>

Resolves the schema and table name from various sources with priority:

1. Explicit schema in table name (e.g., “auth.users”)
2. Header-based (Accept-Profile for GET, Content-Profile for POST/PATCH/DELETE)
3. Default “public” schema

Arguments

• table - Table name, optionally schema-qualified (e.g., “users” or “auth.users”)
• method - HTTP method (GET, POST, PATCH, DELETE)
• headers - Optional headers map containing profile headers

Examples

use postgrest_parser::parser::resolve_schema;
use std::collections::HashMap;

// Explicit schema in table name
let table = resolve_schema("auth.users", "GET", None).unwrap();
assert_eq!(table.schema, "auth");
assert_eq!(table.name, "users");

// Header-based schema
let mut headers = HashMap::new();
headers.insert("Accept-Profile".to_string(), "myschema".to_string());
let table = resolve_schema("users", "GET", Some(&headers)).unwrap();
assert_eq!(table.schema, "myschema");

// Default public schema
let table = resolve_schema("users", "POST", None).unwrap();
assert_eq!(table.schema, "public");
