Enum BoundaryPreset 

pub enum BoundaryPreset {
    Layered,
    Hexagonal,
    FeatureSliced,
    Bulletproof,
}

Built-in architecture presets.

Each preset expands into a set of zones and import rules for a common architecture pattern. User-defined zones and rules merge on top of the preset defaults (zones with the same name replace the preset zone; rules with the same from replace the preset rule).

Examples

use fallow_config::BoundaryPreset;

let preset: BoundaryPreset = serde_json::from_str(r#""layered""#).unwrap();
assert!(matches!(preset, BoundaryPreset::Layered));

Variants

Layered

Classic layered architecture: presentation → application → domain ← infrastructure. Infrastructure may also import from application (common in DI frameworks).

Hexagonal

Hexagonal / ports-and-adapters: adapters → ports → domain.

FeatureSliced

Feature-Sliced Design: app > pages > widgets > features > entities > shared. Each layer may only import from layers below it.

Bulletproof

Bulletproof React: app → features → shared + server. Feature modules are isolated from each other via autoDiscover: every immediate child of src/features/ becomes its own features/<name> zone, and cross-feature imports are reported as boundary violations. Top-level files in src/features/ are classified by the logical features parent zone, so barrels can re-export child features while non-barrel top-level files still obey the features boundary rule.

Implementations

impl BoundaryPreset

pub fn default_config( &self, source_root: &str, ) -> (Vec<BoundaryZone>, Vec<BoundaryRule>)

Expand the preset into default zones and rules.

source_root is the directory prefix for zone patterns (e.g., "src", "lib"). Patterns are generated as {source_root}/{zone_name}/**.

Trait Implementations

impl Clone for BoundaryPreset

fn clone(&self) -> BoundaryPreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundaryPreset

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BoundaryPreset

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for BoundaryPreset

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for BoundaryPreset

fn eq(&self, other: &BoundaryPreset) -> 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.

impl Serialize for BoundaryPreset

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
