Enum Keep 

Source 
pub enum Keep {
    One,
    Any,
    SameSize,
    SameContents,
    Largest,
    Newest,
}
Expand description

How the linker picks the copy of a Group it keeps, in the words gas and llvm-mc take for each of COFF’s selection numbers.

Variants§

§

One

one_only: there must be only one, and two is an error.

§

Any

discard: any one, and the rest are dropped. What a .refptr. pointer is.

§

SameSize

same_size: any one, and two of different sizes are an error.

§

SameContents

same_contents: any one, and two with different bytes are an error.

§

Largest

largest: the biggest one.

§

Newest

newest: the newest one, which no toolchain writes and link.exe does not implement.
