[−][src]Struct char_circle::RawCircle
A thread-safe version of CharCircle
.
The API of this buffer is almost identical to CharCircle
except that it
uses external mutability, and it does not provide a means to consume its
characters from an external iterator.
Methods
impl RawCircle
[src]
ⓘImportant traits for RawCirclepub fn new(s: String) -> RawCircle
[src]
Construct a new RawCircle
using a string as the initial buffer.
ⓘImportant traits for RawCirclepub fn empty() -> RawCircle
[src]
Construct a new, empty RawCircle
.
pub fn len(&self) -> usize
[src]
The number of UTF-8 bytes in the buffer.
pub fn n_chars(&self) -> usize
[src]
The number of characters in the buffer.
pub fn capacity(&self) -> usize
[src]
The number of bytes the buffer can hold before reallocating.
This refers to the length of the backing vector. That vector may have additional capacity allocated to it that is not reported by this method.
pub fn read_char(&mut self) -> Option<char>
[src]
Read the next character in the buffer.
pub fn read(&mut self, buf: &mut [u8]) -> Result<usize>
[src]
Read bytes from this circle into a buffer.
This method will only ever read complete UTF-8 characters. It returns the number of bytes read; it never returns an error.
This is the implementation of std::io::Read
for RawCircle
.
pub fn read_str<'a>(&mut self, buf: &'a mut [u8]) -> &'a str
[src]
Read bytes from this circle into a buffer.
This method is equivalent to RawCircle::read
except the return value
is the buffer cast to a &str
.
pub fn write_char(&mut self, ch: char)
[src]
Write a character into the buffer.
pub fn write(&mut self, buf: &[u8]) -> Result<usize>
[src]
Read bytes from a string into this buffer;
This method will only ever write complete UTF-8 characters. It returns the number of bytes written. This method returns an error if the input is not valid UTF-8.
This is the implementation of std::io::Write
for RawCircle
.
pub fn write_str(&mut self, buf: &str) -> usize
[src]
Read bytes from a string into this buffer;
This method is equivalent to RawCircle::write
except that it cannot return
an error because the input is valid UTF-8.
pub fn into_vec(self) -> Vec<u8>
[src]
Unpack this circular buffer into a byte vector.
pub fn into_string(self) -> String
[src]
Unpack this circular buffer into a string.
