Struct sailfish::runtime::Buffer

pub struct Buffer { /* fields omitted */ }

Buffer for rendered contents

This struct is quite simular to String, but some methods are re-implemented for faster buffering.

Implementations

impl Buffer

pub const fn new() -> Buffer

pub fn with_capacity(n: usize) -> Buffer

pub fn as_str(&self) -> &str

pub fn len(&self) -> usize

pub fn capacity(&self) -> usize

pub unsafe fn set_len(&mut self, new_len: usize)

Force the length of buffer to new_len

Safety

• new_len must be less than or equal to capacity()
• The elements at old_len..new_len must be initialized

pub fn is_empty(&self) -> bool

pub fn reserve(&mut self, size: usize)

pub fn clear(&mut self)

pub fn into_string(self) -> String

pub fn write_str(&mut self, data: &str)

pub fn write_char(&mut self, data: char)

Trait Implementations

impl<'_> Add<&'_ str> for Buffer

type Output = Buffer

The resulting type after applying the + operator.

fn add(self, other: &str) -> Buffer

Performs the + operation.

impl<'_> AddAssign<&'_ str> for Buffer

fn add_assign(&mut self, other: &str)

Performs the += operation.

impl Clone for Buffer

fn clone(&self) -> Buffer

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Buffer

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for Buffer

fn default() -> Buffer

Returns the "default value" for a type.

impl Drop for Buffer

fn drop(&mut self)

Executes the destructor for this type.

impl<'_> From<&'_ str> for Buffer

fn from(other: &str) -> Buffer

Performs the conversion.

impl From<String> for Buffer

fn from(other: String) -> Buffer

Performs the conversion.

impl Write for Buffer

fn write_str(&mut self, s: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a [char] into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments) -> Result<(), Error>

Glue for usage of the [write!] macro with implementors of this trait.
