Struct SwiftBackend 

pub struct SwiftBackend {
    pub emit_public: bool,
    pub emit_comments: bool,
    /* private fields */
}

Swift code generation backend.

Compiles LCNF declarations/expressions to valid Swift source code. Entry points:

• SwiftBackend::compile_module — compile a complete LcnfDecl collection
• SwiftBackend::compile_decl — compile a single LcnfDecl
• SwiftBackend::compile_expr — compile an LcnfExpr
• SwiftBackend::mangle_name — escape an OxiLean identifier for Swift

Fields

emit_public: bool

Whether to emit public declarations

emit_comments: bool

Whether to emit inline comments

Implementations

impl SwiftBackend

pub fn new() -> Self

Create a new backend with default settings.

pub fn fresh_var(&mut self) -> String

Allocate a fresh temporary variable name.

pub fn mangle_name(name: &str) -> String

Mangle an OxiLean name into a valid Swift identifier.

Rules:

1. Empty input → "ox_empty"
2. Swift keywords → prefixed with ox_
3. Leading digit → prefixed with ox_
4. Non-alphanumeric / non-underscore characters → replaced with _

pub fn compile_arg(&self, arg: &LcnfArg) -> SwiftExpr

Compile an LCNF argument to a Swift expression.

pub fn compile_lit(&self, lit: &LcnfLit) -> SwiftExpr

Compile an LCNF literal to a Swift expression.

pub fn compile_expr(&self, expr: &LcnfExpr) -> Vec<SwiftStmt>

Compile an LCNF expression to a list of Swift statements.

The final statement is always a return.

pub fn compile_let_value(&self, value: &LcnfLetValue) -> SwiftExpr

Compile a let-value to a Swift expression.

pub fn compile_decl(&self, decl: &LcnfFunDecl) -> SwiftFunc

Compile a single LCNF function declaration to a SwiftFunc.

pub fn compile_lcnf_type(&self, ty: &LcnfType) -> SwiftType

Map an LCNF type to the closest Swift type.

pub fn compile_module(&self, name: &str, decls: &[LcnfFunDecl]) -> SwiftModule

Compile a collection of LCNF declarations into a SwiftModule.

pub fn emit_module(&self, module: &SwiftModule) -> String

Emit a SwiftModule to a Swift source string.

pub fn emit_func(&self, func: &SwiftFunc) -> String

Emit a single SwiftFunc to a Swift source string.

pub fn emit_type_decl(&self, decl: &SwiftTypeDecl) -> String

Emit a single SwiftTypeDecl to a Swift source string.

Trait Implementations

impl Default for SwiftBackend

fn default() -> Self

Returns the “default value” for a type.
