Struct Structure

pub struct Structure<'a> { /* private fields */ }

Structure validator

In yaml terms this validates that value is a map (or a null value, if all defaults are okay).

Additionally this validator allows to parse some scalar and convert it to the structure. This feature is useful to upgrade scalar value to a structure maintaining backwards compatiblity as well as for configuring common case more easily.

Implementations

impl<'a> Structure<'a>

pub fn new() -> Structure<'a>

pub fn member<S: Display, V: Validator + 'a>( self, name: S, value: V, ) -> Structure<'a>

pub fn optional(self) -> Structure<'a>

pub fn parser( self, f: fn(scalar: Ast) -> BTreeMap<String, Ast>, ) -> Structure<'a>

Trait Implementations

impl<'a> Validator for Structure<'a>

fn default(&self, pos: Pos) -> Option<Ast>
