Struct StackStr 

struct StackStr<const N: usize> {
    buf: [u8; N],
    len: usize,
}

Stack-only string buffer to avoid heap allocation in the status-line path.

Fields

buf: [u8; N]

len: usize

Implementations

impl<const N: usize> StackStr<N>

const fn new() -> Self

Creates a new instance.

fn is_empty(&self) -> bool

fn char_len(&self) -> usize

fn push_str(&mut self, s: &str)

fn push_char(&mut self, ch: char)

Returns this as str.

Trait Implementations

impl<const N: usize> Display for StackStr<N>

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

Performs the fmt operation.

impl<const N: usize> Write for StackStr<N>

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