Methods
impl RString
[src]
pub fn new() -> Self
[src]
pub fn with_capacity(cap: usize) -> Self
[src]
pub fn slice<'a, I>(&'a self, i: I) -> RStr<'a> where
str: Index<I, Output = str>,
[src]
str: Index<I, Output = str>,
For slicing into RStr
s.
This is an inherent method instead of an implementation of the ::std::ops::Index trait because it does not return a reference.

[src]
pub fn into_string(self) -> String
[src]

Allocation
If this is invoked outside of the dynamic library/binary that created it,
it will allocate a new String
and move the data into it.

Copies the RString
into a String
.
