Implementations

impl<const N: usize> TinyAsciiStr<N>

pub const fn from_bytes(bytes: &[u8]) -> Result<Self, TinyStrError>

Creates a TinyAsciiStr<N> from the given byte slice. bytes may contain at most N non-null ASCII bytes.

pub const fn from_bytes_lossy(bytes: &[u8]) -> Self

Creates a TinyAsciiStr<N> from a byte slice, replacing invalid bytes.

Null and non-ASCII bytes (i.e. those outside the range 0x01..=0x7F) will be replaced with the ‘?’ character.

The input slice will be truncated if its length exceeds N.

pub const fn try_from_raw(raw: [u8; N]) -> Result<Self, TinyStrError>

Attempts to parse a fixed-length byte array to a TinyAsciiStr.

The byte array may contain trailing NUL bytes.

Example

use tinystr::tinystr;
use tinystr::TinyAsciiStr;

assert_eq!(
    TinyAsciiStr::<3>::try_from_raw(*b"GB\0"),
    Ok(tinystr!(3, "GB"))
);
assert_eq!(
    TinyAsciiStr::<3>::try_from_raw(*b"USD"),
    Ok(tinystr!(3, "USD"))
);
assert!(matches!(TinyAsciiStr::<3>::try_from_raw(*b"\0A\0"), Err(_)));

pub const fn from_bytes_manual_slice( bytes: &[u8], start: usize, end: usize, ) -> Result<Self, TinyStrError>

Equivalent to from_bytes(bytes[start..end]), but callable in a const context (which range indexing is not).

pub const fn from_str(s: &str) -> Result<Self, TinyStrError>

pub const fn as_str(&self) -> &str

pub const fn len(&self) -> usize

pub const fn is_empty(&self) -> bool

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

pub const fn all_bytes(&self) -> &[u8; N]

pub const fn resize<const M: usize>(self) -> TinyAsciiStr<M>

Resizes a TinyAsciiStr<N> to a TinyAsciiStr<M>.

If M < len() the string gets truncated, otherwise only the memory representation changes.

pub const unsafe fn from_bytes_unchecked(bytes: [u8; N]) -> Self

Safety

Must be called with a bytes array made of valid ASCII bytes, with no null bytes between ASCII characters
