impl<'a> FetchTarget<'a, Need> for NeedTarget

fn fetch_values( &self, spec: &'a Specification, ) -> Result<&'a [Need], TargetError<Self>>

Fetch the map reference containing the targeted item.

fn fetch_values_mut( &self, spec: &'a mut Specification, ) -> Result<&'a mut [Need], TargetError<Self>>

Fetch the mutable map reference containing the targeted item.

fn index(&self) -> usize

The index to access in the selected map.

fn fetch(&self, spec: &'a Specification) -> Result<&'a V, TargetError<Self>>

Fetch a reference to the target from the specification.

fn fetch_mut( &self, spec: &'a mut Specification, ) -> Result<&'a mut V, TargetError<Self>>

impl PartialEq for Need

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
