Struct GeneralString 

pub struct GeneralString(pub Vec<u8>);

ASN.1 GeneralString (tag 27)

An 8-bit character set. In practice (Kerberos, X.500) this is used as Latin-1 or ASCII. No character set validation is performed; bytes are exposed raw.

Tuple Fields

0: Vec<u8>

Implementations

impl GeneralString

pub fn new(bytes: Vec<u8>) -> Self

Create a new GeneralString from raw bytes.

pub fn from_ascii(s: &str) -> Result<Self>

Create a new GeneralString from an ASCII string slice.

Returns an error if any character is outside the ASCII range (U+0000..=U+007F). The bytes are copied with a single memcpy; no per-character processing is needed because ASCII code points equal their UTF-8 byte representations.

pub fn from_ascii_string(s: String) -> Result<Self>

Create a new GeneralString from an owned ASCII String.

Returns an error if any character is outside the ASCII range (U+0000..=U+007F).

On success the String’s heap buffer is reused directly via String::into_bytes; no extra allocation is performed.

pub fn from_str_lossy(s: &str) -> Self

Create a new GeneralString from a string, encoding it as Latin-1 (lossy).

Characters above U+00FF are silently truncated to their low 8 bits. Prefer GeneralString::from_ascii which returns an error for out-of-range characters.

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

Get the raw bytes.

pub fn as_latin1_string(&self) -> String

Decode the bytes as a Latin-1 string.

pub fn into_vec(self) -> Vec<u8>

Convert into the inner Vec.

Trait Implementations

impl Clone for GeneralString

fn clone(&self) -> GeneralString

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeneralString

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

Formats the value using the given formatter.

impl Decode<'_> for GeneralString

fn decode(decoder: &mut Decoder<'_>) -> Result<Self>

Decode one ASN.1 value from decoder.

impl Encode for GeneralString

fn encode(&self, encoder: &mut Encoder) -> Result<()>

Encode this value as ASN.1 TLV bytes into encoder.

fn encoded_len(&self) -> Result<usize>

Return the number of bytes that encode will write.

impl PartialEq for GeneralString

fn eq(&self, other: &GeneralString) -> 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.

impl Tagged for GeneralString

fn tag() -> Tag

Return the outermost ASN.1 tag for this type.
