pub struct Lookahead<'a> { /* private fields */ }
Expand description

A selection performed by a query.

Implementations

Get the field of the selection set with the specified name. This will ignore aliases.

For example, calling .field("a") on { a { b } } will return a lookahead that represents { b }.

Returns true if field exists otherwise return false.

Get the SelectionFields for each of the fields covered by this Lookahead.

There will be multiple fields in situations where the same field is queried twice.

Trait Implementations

Converts to this type from the input type.

Convert a slice of SelectionFields to a Lookahead. Assumes all SelectionFields are from the same query and thus have the same fragments.

Fails if either no SelectionFields were provided.

The type returned in the event of a conversion error.

Performs the conversion.
