Struct DhallDecl 

pub struct DhallDecl {
    pub name: String,
    pub ty: Option<DhallType>,
    pub value: DhallExpr,
}

A top-level Dhall declaration (inside a let chain or file).

Fields

name: String

Bound name

ty: Option<DhallType>

Optional type annotation

value: DhallExpr

Value expression

Implementations

impl DhallDecl

pub fn new(name: impl Into<String>, value: DhallExpr) -> Self

Create a declaration without a type annotation.

pub fn typed(name: impl Into<String>, ty: DhallType, value: DhallExpr) -> Self

Create a declaration with a type annotation.

Trait Implementations

impl Clone for DhallDecl

fn clone(&self) -> DhallDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DhallDecl

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

Formats the value using the given formatter.

impl PartialEq for DhallDecl

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