Struct TableValidator 

pub struct TableValidator;

Table validator

Implementations

impl TableValidator

pub fn new() -> Self

Create a new table validator

Example

use data_modelling_core::validation::tables::TableValidator;

let validator = TableValidator::new();

pub fn detect_naming_conflicts( &self, existing_tables: &[Table], new_tables: &[Table], ) -> Vec<NamingConflict>

Detect naming conflicts between new tables and existing tables

The logic checks for conflicts using unique keys: (database_type, name, catalog_name, schema_name)

Arguments

• existing_tables - Tables that already exist
• new_tables - New tables to check for conflicts

Returns

A vector of NamingConflict structs for each conflict found.

Example

use data_modelling_core::validation::tables::TableValidator;
use data_modelling_core::models::{Table, Column};

let validator = TableValidator::new();
let existing = vec![Table::new("users".to_string(), vec![])];
let new_tables = vec![Table::new("users".to_string(), vec![])];

let conflicts = validator.detect_naming_conflicts(&existing, &new_tables);
assert_eq!(conflicts.len(), 1);

pub fn validate_pattern_exclusivity( &self, table: &Table, ) -> Result<(), PatternViolation>

Validate pattern exclusivity (SCD pattern and Data Vault classification are mutually exclusive)

Arguments

• table - The table to validate

Returns

Ok(()) if valid, Err(PatternViolation) if both SCD pattern and Data Vault classification are set.

Example

use data_modelling_core::validation::tables::TableValidator;
use data_modelling_core::models::{Table, Column};
use data_modelling_core::models::enums::{SCDPattern, DataVaultClassification};

let validator = TableValidator::new();
let mut table = Table::new("test".to_string(), vec![]);
table.scd_pattern = Some(SCDPattern::Type2);
table.data_vault_classification = Some(DataVaultClassification::Hub);

let result = validator.validate_pattern_exclusivity(&table);
assert!(result.is_err());

Trait Implementations

impl Default for TableValidator

fn default() -> TableValidator
