Struct FixedText 

pub struct FixedText<const N: usize> { /* private fields */ }

A C string of at most N - 1 bytes written with fmt::Write, without allocating: the panic handler’s message, which must not fail when the heap is what ran out. Text that doesn’t fit is cut at a character boundary; NULs are left out. N is at least 1.

Implementations

impl<const N: usize> FixedText<N>

pub const fn new() -> Self

Empty text.

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

The text so far with its NUL, for the SDK.

Trait Implementations

impl<const N: usize> Debug for FixedText<N>

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

Formats the value using the given formatter.

impl<const N: usize> Default for FixedText<N>

fn default() -> Self

Returns the “default value” for a type.

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

fn write_str(&mut self, text: &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.
