Struct FieldDefExtras 

pub struct FieldDefExtras {
    pub safety: Safety,
    pub mut_restriction: MutRestriction,
    pub default: Option<AnonConst>,
}

Some properties from FieldDef are rarely used, so we outline them to make FieldDef smaller. At the time of writing, these are all related to unstable features.

Fields

safety: Safety

mut_restriction: MutRestriction

default: Option<AnonConst>

Layout

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.
