Struct noak::mutf8::MString

pub struct MString { /* private fields */ }

A Modified UTF-8 string, but owned, like String.

Implementations

impl MString

pub fn new() -> MString

Creates an empty string.

pub fn with_capacity(cap: usize) -> MString

Creates an empty string with capacity.

pub fn from_mutf8(buf: Vec<u8>) -> Result<MString, DecodeError>

Creates a new string from a modified UTF-8 byte vector.

pub fn push(&mut self, ch: char)

Pushes a character to the string. It might cause a reallocation.

Methods from Deref<Target = MStr>

pub fn len(&self) -> usize

Returns the length of the string in bytes.

pub fn is_empty(&self) -> bool

Returns whether the string contains any characters.

pub fn as_bytes(&self) -> &[u8]

Returns the inner byte slice.

pub fn to_str(&self) -> Option<&str>

Checks whether the modified UTF-8 string is valid UTF-8 and returns a &str if it is.

pub fn is_char_boundary(&self, index: usize) -> bool

Returns whether the index-th byte is the first byte of a modified UTF-8 code point sequence or the end of the string.

pub fn chars(&self) -> Chars<'_>

Returns an iterator over the chars in this string.

For valid unicode characters, Ok is yielded. If a character is invalid, then its code will be returned in the Err case. If you don’t care about invalid characters, use chars_lossy.

pub fn chars_lossy(&self) -> CharsLossy<'_>

Returns an iterator over the chars in this string.

Invalid characters are replaced with U+FFFD (char::REPLACEMENT_CHARACTER).

pub fn display(&self) -> Display<'_>

Provides a value of a type that implements Display.

Invalid characters are displayed as U+FFFD (char::REPLACEMENT_CHARACTER).
