Enum GenericUsage 

enum GenericUsage {
    Absent,
    Bare,
    InContainer(TypePath),
}

How a generic type parameter T appears in a type.

Variants

Absent

T does not appear in this type.

Bare

T appears bare (possibly wrapped in Option or Result).

InContainer(TypePath)

T appears inside a container type (e.g. DatumList<'a, T>, Array<'a, T>). The stored syn::TypePath is the container with T erased to Datum<'a>.

Trait Implementations

impl Clone for GenericUsage

fn clone(&self) -> GenericUsage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GenericUsage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for GenericUsage

fn eq(&self, other: &Self) -> 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.
