🔬This is a nightly-only experimental API. (transmutability)
Expand description

What transmutation safety conditions shall the compiler assume that you are checking?

Fields§

§alignment: bool
🔬This is a nightly-only experimental API. (transmutability)

When true, the compiler assumes that you are ensuring (either dynamically or statically) that destination referents do not have stricter alignment requirements than source referents.

§lifetimes: bool
🔬This is a nightly-only experimental API. (transmutability)

When true, the compiler assume that you are ensuring that lifetimes are not extended in a manner that violates Rust’s memory model.

§safety: bool
🔬This is a nightly-only experimental API. (transmutability)

When true, the compiler assumes that you have ensured that it is safe for you to violate the type and field privacy of the destination type (and sometimes of the source type, too).

§validity: bool
🔬This is a nightly-only experimental API. (transmutability)

When true, the compiler assumes that you are ensuring that the source type is actually a valid instance of the destination type.
