Enum RefKind 

#[non_exhaustive]
pub enum RefKind {
    None,
    Ref,
    Rev,
    Both,
}

Discriminates the four ref/rev presence states without forcing callers to read both FlakeRef::ref_ and FlakeRef::rev and reason about the cross product.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

None

Neither ref_ nor rev is set.

Ref

Only ref_ is set (a branch or tag name, not a 40-hex commit hash).

Rev

Only rev is set (pinned to a 40-hex commit hash).

Both

Both ref_ and rev are set (canonical Nix’s three-segment Indirect form, flake:id/ref/rev).

Trait Implementations

impl Clone for RefKind

fn clone(&self) -> RefKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RefKind

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

Formats the value using the given formatter.

impl PartialEq for RefKind

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