Function put_text_property

pub fn put_text_property<'ob>(
    start: usize,
    end: usize,
    property: Gc<ObjectType<'ob>>,
    value: Gc<ObjectType<'ob>>,
    object: Gc<ObjectType<'ob>>,
    env: &mut Rt<Env<'_>>,
    cx: &'ob Context<'_>,
) -> Result<()>

Set one property of the text from START to END. The third and fourth arguments PROPERTY and VALUE specify the property to add. If the optional fifth argument OBJECT is a buffer (or nil, which means the current buffer), START and END are buffer positions (integers or markers). If OBJECT is a string, START and END are 0-based indices into it.
