Struct rustc_apfloat::Status

pub struct Status {
    pub(crate) bits: u8,
}

IEEE-754R 7: Default exception handling.

UNDERFLOW or OVERFLOW are always returned or-ed with INEXACT.

Fields

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
