Struct FieldDecl 

pub struct FieldDecl {
    pub name: String,
    pub type_hint: Option<String>,
    pub constraints: Constraints,
    pub block: bool,
}

One declaration from a !fields line: name(type)[constraints].

Fields

name: String

Field name. Compared by exact Unicode scalar sequence (§5.1).

type_hint: Option<String>

The (type) production only. type:<name> lives in constraints; use FieldDecl::type_name for the effective hint (§8.2).

constraints: Constraints

Parsed by the SYNX constraint parser (§5.2). Not enforced unless the caller opts into validating mode (§8.4).

block: bool

The SYNXL-only block flag (§5.3).

Implementations

impl FieldDecl

pub fn new(name: impl Into<String>) -> FieldDecl

A plain, untyped, unconstrained field.

pub fn new_block(name: impl Into<String>) -> FieldDecl

The same, flagged [block] (§5.3).

pub fn type_name(&self) -> Option<&str>

Effective type hint: (type) wins over type:<name> (§8.2).

Trait Implementations

impl Clone for FieldDecl

fn clone(&self) -> FieldDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldDecl

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

Formats the value using the given formatter.

impl PartialEq for FieldDecl

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

Equality operator ==.

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

Inequality operator !=.
