Enum rustc_mir_build::check_unsafety::BodyUnsafety

source · [−]

enum BodyUnsafety {
    Safe,
    Unsafe(Span),
}

Variants

`Safe`

The body is not unsafe.

`Unsafe(Span)`

The body is an unsafe function. The span points to the signature of the function.

Implementations

source

impl BodyUnsafety

source

fn is_unsafe(&self) -> bool

Returns whether the body is unsafe.

source

fn unsafe_fn_sig_span(self) -> Option

If the body is unsafe, returns the Span of its signature.
