Overwrites the data area to which the vector points.
Scatter limit bytes of data from the location at p into the locations identified by this vector.
§ copy_from() [2/3]
Overwrites the data area to which the vector points.
Write data from the vector v into the locations identified by this vector.
§ copy_from() [3/3]
Overwrites the data area to which the vector points.
Write data from the vector v, starting at the given offset from the start of vector v, into the locations identified by this vector.
§ len()
|
inline |
Return the length from the {pointer, length} pair at the given index.
§ operator=()
§ ptr()
|
inline |
Return the pointer from the {pointer, length} pair at the given index.
