ManyToMany relationship metadata

This structure holds specific metadata for ManyToMany relationships, including through table information and custom field names.

Fields

field_name: String

Field name

to_model: String

Target model name (e.g., “Group”, “User”)

related_name: Option<String>

Related name for reverse accessor

through: Option<String>

Custom through table name (if specified)

source_field: Option<String>

Source field name in through table (defaults to “{source_model}_id”)

target_field: Option<String>

Target field name in through table (defaults to “{target_model}_id”)

db_constraint_prefix: Option<String>

Database constraint prefix

Implementations

impl ManyToManyMetadata

pub fn new( field_name: impl Into<String>, to_model: impl Into<String>, ) -> ManyToManyMetadata

Create a new ManyToManyMetadata

pub fn with_related_name( self, related_name: impl Into<String>, ) -> ManyToManyMetadata

Set related name

pub fn with_through(self, through: impl Into<String>) -> ManyToManyMetadata

Set through table name

pub fn with_source_field( self, source_field: impl Into<String>, ) -> ManyToManyMetadata

Set source field name

pub fn with_target_field( self, target_field: impl Into<String>, ) -> ManyToManyMetadata

Set target field name

pub fn with_db_constraint_prefix( self, prefix: impl Into<String>, ) -> ManyToManyMetadata

Set database constraint prefix

Trait Implementations

impl Clone for ManyToManyMetadata

fn clone(&self) -> ManyToManyMetadata

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ManyToManyMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ManyToManyMetadata

fn eq(&self, other: &ManyToManyMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
