Enum LinearDiscipline 

#[non_exhaustive]
pub enum LinearDiscipline {
    Linear,
    Affine,
    Relevant,
    Unrestricted,
}

Substructural-type discipline applied to one buffer or value.

Mirrors vyre_foundation::ir::LinearType but lives at the primitive layer so external crates (the type-checker pass, future effect-system frontends, external analyzer rule lowering) can refer to the discipline without pulling in the IR.

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.

Linear

Exactly one use. uses == 1 is the only legal count.

Affine

At most one use. uses <= 1.

Relevant

At least one use. uses >= 1.

Unrestricted

No discipline. Any uses count is permitted.

Implementations

impl LinearDiscipline

pub const fn forbids_drop(self) -> bool

Whether this discipline forbids dropping a buffer without using it (Linear or Relevant).

pub const fn forbids_reuse(self) -> bool

Whether this discipline forbids using a buffer more than once (Linear or Affine).
