Struct FixedFilename 

pub struct FixedFilename<const N: usize> {
    pub data: [u8; N],
    pub len: usize,
}

A fixed-length, stack-allocated filename buffer.

Stores up to N bytes of filename data on the stack without heap allocation. Useful for no-std filesystem implementations where filenames have a known maximum length.

Example

use hadris_common::types::file::FixedFilename;

let name = FixedFilename::<64>::from(b"readme.txt".as_slice());
assert_eq!(name.len(), 10);
assert_eq!(name.as_str(), "readme.txt");
assert!(!name.is_empty());

Fields

data: [u8; N]

len: usize

Trait Implementations

impl<const N: usize> Clone for FixedFilename<N>

fn clone(&self) -> FixedFilename<N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

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

Formats the value using the given formatter.

impl<const N: usize> From<&[u8]> for FixedFilename<N>

fn from(value: &[u8]) -> Self

Converts to this type from the input type.

impl<const N: usize> PartialEq for FixedFilename<N>

fn eq(&self, other: &FixedFilename<N>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
