Enum DefinitionSafety 

pub enum DefinitionSafety {
    Safe,
    Unsafe,
    Partial,
}

Safety classification for definitions.

Variants

Safe

Safe: pure and terminating.

Unsafe

Unsafe: may use unsafe declarations.

Partial

Partial: may not terminate.

Implementations

impl DefinitionSafety

pub fn is_safe(&self) -> bool

Whether this safety level is safe (not partial or unsafe).

pub fn is_partial(&self) -> bool

Whether this definition is partial (allows general recursion).

pub fn as_str(&self) -> &'static str

Return a human-readable string for the safety level.

Trait Implementations

impl Clone for DefinitionSafety

fn clone(&self) -> DefinitionSafety

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DefinitionSafety

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

Formats the value using the given formatter.

impl Hash for DefinitionSafety

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DefinitionSafety

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