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.
