Struct Charset

pub struct Charset<'a>(pub &'a str);

Represents a struct for handling both encode and decode of strings using a custom character set (charset). This struct provides methods to encode and decode strings based on the provided charset.

Fields

• charset: A reference to the character set used for encoding and decoding. Each character in the charset should be unique and ideally contain exactly 64 characters for base64-like encoding.

Lifetimes

• 'a: The lifetime 'a is associated with charset, ensuring that the charset reference lives at least as long as the Charset instance.

Tuple Fields

0: &'a str

Implementations

impl<'a> Charset<'a>

pub fn new() -> Charset<'a>

Creates a new instance of Charset with a default charset.

pub fn charset<'b>(&mut self, charset: &'b str) -> &mut Charset<'a>

where 'b: 'a,

Sets the charset for the current Charset instance, if it is not already set.

Parameters

• charset: A string slice representing the charset to be used.

Returns

Returns a mutable reference to Self for method chaining.

pub fn encode(&self, encode_str: &str) -> Result<String, EncodeError>

encodes a string based on the current charset.

Parameters

• encode_str: The string slice to be encoded.

Returns

Returns a Result containing the encoded String if successful, or a EncodeError if the charset is invalid.

pub fn decode(&self, decode_str: &str) -> Result<String, DecodeError>

decodes a string based on the current charset.

Parameters

• decode_str: The string slice to be decoded.

Returns

Returns a Result containing the decoded String if successful, or a DecodeError if the charset is invalid.

Trait Implementations

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

Performs copy-assignment from source.

impl<'a> Debug for Charset<'a>

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

impl<'a> Default for Charset<'a>

fn default() -> Charset<'a>

Returns the “default value” for a type.
