unsafe fn buf_as_slice<T>(buf: *u8, len: uint, f: &fn(v: &str) -> T) -> T
Form a slice from a *u8 buffer of the given length without copying.
from_buf
unsafe fn from_buf(buf: *u8) -> ~str
Create a Rust string from a null-terminated *u8 buffer
from_buf_len
unsafe fn from_buf_len(buf: *const u8, len: uint) -> ~str
Create a Rust string from a *u8 buffer of the given length
from_byte
unsafe fn from_byte(u: u8) -> ~str
Converts a byte to a string.
from_bytes
unsafe fn from_bytes(v: &const [u8]) -> ~str
Converts a vector of bytes to a string.
from_c_str
unsafe fn from_c_str(c_str: *libc::c_char) -> ~str
Create a Rust string from a null-terminated C string
from_c_str_len
unsafe fn from_c_str_len(c_str: *libc::c_char, len: uint) -> ~str
Create a Rust string from a *c_char
buffer of the given length
pop_byte
unsafe fn pop_byte(s: &mut ~str) -> u8
Removes the last byte from a string and returns it. (Not UTF-8 safe).
push_byte
unsafe fn push_byte(s: &mut ~str, b: u8)
Appends a byte to a string. (Not UTF-8 safe).
set_len
unsafe fn set_len(v: &mut ~str, new_len: uint)
Sets the length of the string and adds the null terminator
shift_byte
unsafe fn shift_byte(s: &mut ~str) -> u8
Removes the first byte from a string and returns it. (Not UTF-8 safe).
slice_bytes
unsafe fn slice_bytes(s: &str, begin: uint, end: uint) -> &str
Takes a bytewise (not UTF-8) slice from a string.
Returns the substring from [begin
..end
).
If begin is greater than end. If end is greater than the length of the string.
slice_bytes_unique
unsafe fn slice_bytes_unique(s: &str, begin: uint, end: uint) -> ~str
Takes a bytewise (not UTF-8) slice from a string.
Returns the substring from [begin
..end
).
If begin is greater than end. If end is greater than the length of the string.
