Struct FormattedBytes 

pub struct FormattedBytes { /* private fields */ }

A stack-allocated buffer containing the formatted byte string.

FormattedBytes calculates the formatting upon instantiation and stores the result internally. It can be cheaply converted to a &str or &[u8].

Implementations

impl FormattedBytes

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

Returns the formatted output as a raw byte slice. Useful for direct std::io::Write usage.

pub fn as_str(&self) -> Result<&str, Utf8Error>

Returns the formatted output as a UTF-8 string slice.

Errors

Returns a core::str::Utf8Error if the internal buffer contains invalid UTF-8 bytes. (Note: The format method only writes valid ASCII characters, so this is guaranteed to succeed in practice).

Trait Implementations

impl Clone for FormattedBytes

fn clone(&self) -> FormattedBytes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Display for FormattedBytes

Allows FormattedBytes to be used in standard Rust formatting macros (e.g., format!(), println!(), write!()).

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

Formats the value using the given formatter.

impl Format for FormattedBytes

Available on crate feature defmt only.

Allow FormattedBytes to be logged seamlessly in resource-constrained embedded environments using the defmt framework.

fn format(&self, fmt: Formatter<'_>)

Writes the defmt representation of self to fmt.
