Struct ValueOptions 

pub struct ValueOptions {
    pub negative_numbers: bool,
    pub hyphen_values: bool,
    pub require_equals: bool,
    pub keep_equals: bool,
}

How a flag takes a detached value, beyond the default of any word that is not flag-like.

More options may be added: build one from ValueOptions::DEFAULT (ValueOptions { hyphen_values: true, ..ValueOptions::DEFAULT }).

Fields

negative_numbers: bool

A negative number is a value, not a flag: --offset -1.

hyphen_values: bool

Any next word is the value, -- and flag-like ones included: --args -x.

require_equals: bool

Only an attached value: --inspect=9229, -i9229; the next word is never taken.

keep_equals: bool

A short option’s attached value keeps a leading =: -L=dir is =dir, as GNU ld reads it (a sysroot-relative path), not dir.

Implementations
