Struct Buffer

pub struct Buffer<T> { /* private fields */ }

Static buffer to hold written text.

Implementation of ToStr must write it from the end.

Implementations

impl<S: Sized> Buffer<S>

pub const fn new() -> Self

Creates new instance

pub const fn as_ptr(&self) -> *const u8

Returns pointer to the beginning of underlying buffer

pub const fn capacity() -> usize

Returns buffer overall capacity.

pub fn as_str(&self) -> &str

Access str from underlying storage

Returns empty if nothing has been written into buffer yet.

pub fn write<T: ToStr>(&mut self, val: T) -> &str

Formats value into buffer, returning text.

Buffer remembers the write, therefore as_str() will return the same text as last write

pub fn format<T: ToStr>(&mut self, val: T) -> &str

Formats value into buffer, returning text.

Buffer remains unaware of modifications

pub fn fmt<T: ToStr>(val: T) -> Self

Creates new instance with formatted value.

Trait Implementations

impl<S: Sized> AsRef<str> for Buffer<S>

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl<S: Sized> Debug for Buffer<S>

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

Formats the value using the given formatter.

impl<S: Sized> Display for Buffer<S>

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

Formats the value using the given formatter.
