Enum git_attributes::StateRef

pub enum StateRef<'a> {
    Set,
    Unset,
    Value(&'a BStr),
    Unspecified,
}

The state an attribute can be in, referencing the value.

Note that this doesn’t contain the name.

Variants

Set

The attribute is listed, or has the special value ‘true’

Unset

The attribute has the special value ‘false’, or was prefixed with a - sign.

Value(&'a BStr)

The attribute is set to the given value, which followed the = sign. Note that values can be empty.

Unspecified

The attribute isn’t mentioned with a given path or is explicitly set to Unspecified using the ! sign.
