Struct attr::MapPath

pub struct MapPath<A, R> { /* fields omitted */ }

A path that describes a mapping operation, which later application of a subpath.

Paths are usually inferred and should not be directly used in user code.

Methods

impl<A, R> MapPath<A, R>

fn from<'a, 'b: 'a, X: 'b, Y: 'b, Z: 'b, NX: 'b, NY: 'b, NA>(
    self,
    attr: NA
) -> Path<NX, Box<Iterator<Item = Result<Z>> + 'a>, NA, Self> where
    A: IterableAttr<'a, X, Item = Y>,
    R: Traverse<'a, 'b, Y, Z>,
    NA: Attr<NX, Output = NY>,
    Self: Traverse<'a, 'b, NY, Box<Iterator<Item = Result<Z>>>>, 

Extends a mapped path by another segment that always succeeds

Trait Implementations

impl<'a, X: 'a, Z: 'a, A: IterableAttr<'a, X>, R: Traverse<'a, 'a, A::Item, Z>> Traverse<'a, 'a, X, Box<Iterator<Item = Result<Z>> + 'a>> for MapPath<A, R>

fn traverse(&'a self, obj: X) -> Result<Box<Iterator<Item = Result<Z>> + 'a>>

implementation of the traversal for a specific path
