Path

Struct Path 

Source
pub struct Path<T, V> { /* private fields */ }
Expand description

A path into a document, what its index can be asked, and the type of the value that lives there.

Written by #[derive(Yo)] as a constant per indexed field, so a query names the field rather than spelling a string the compiler cannot check. A field marked #[yo(ordered)] gets an Ordered instead, which is the same thing with ranges on it.

Implementations§

Source§

impl<T, V> Path<T, V>

Source

pub const fn new(path: &'static str, kind: IndexKind) -> Path<T, V>

A path and what its index answers.

The derive calls this. Calling it by hand is allowed and is how a path into a nested object is reached until the derive learns to follow one, but nothing checks that the collection has the index you named until the query runs.

Source

pub const fn path(&self) -> &'static str

The path, as $.status.

Source

pub const fn kind(&self) -> IndexKind

What the index on this path can be asked.

impl<T, V> From<Ordered<T, V>> for Path<T, V>
