Struct EncodeBuilder 

pub struct EncodeBuilder<'a, I>
where
    I: AsRef<[u8]>,
{ /* private fields */ }

A builder for setting up the alphabet and output of a base58 encode.

Implementations

impl<'a, I> EncodeBuilder<'a, I>

where I: AsRef<[u8]>,

pub fn new(input: I, alpha: &'a Alphabet) -> EncodeBuilder<'a, I>

Setup encoder for the given string using the given alphabet. Preferably use bs58::encode instead of this directly.

pub fn with_alphabet(self, alpha: &'a Alphabet) -> EncodeBuilder<'a, I>

Change the alphabet that will be used for encoding.

Examples

let input = [0x60, 0x65, 0xe7, 0x9b, 0xba, 0x2f, 0x78];
assert_eq!(
    "he11owor1d",
    bs58::encode(input)
        .with_alphabet(bs58::Alphabet::RIPPLE)
        .into_string());

pub fn into_string(self) -> String

Encode into a new owned string.

Examples

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
assert_eq!("he11owor1d", bs58::encode(input).into_string());

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

Encode into a new owned vector.

Examples

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
assert_eq!(b"he11owor1d", &*bs58::encode(input).into_vec());

pub fn into(self, output: impl EncodeTarget) -> Result<usize, Error>

Encode into the given buffer.

Returns the length written into the buffer.

If the buffer is resizeable it will be reallocated to fit the encoded data and truncated to size.

If the buffer is not resizeable bytes after the final character will be left alone, except up to 3 null bytes may be written to an &mut str to overwrite remaining characters of a partially overwritten multi-byte character.

See the documentation for bs58::encode for an explanation of the errors that may occur.

Examples

Vec<u8>

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
let mut output = "goodbye world".to_owned().into_bytes();
bs58::encode(input).into(&mut output)?;
assert_eq!(b"he11owor1d", &*output);

&mut [u8]

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
let mut output = Vec::from("goodbye world");
bs58::encode(input).into(&mut output[..])?;
assert_eq!(b"he11owor1drld", &*output);

String

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
let mut output = "goodbye world".to_owned();
bs58::encode(input).into(&mut output)?;
assert_eq!("he11owor1d", output);

&mut str

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
let mut output = "goodbye world".to_owned();
bs58::encode(input).into(output.as_mut_str())?;
assert_eq!("he11owor1drld", output);

Clearing partially overwritten characters

let input = [0x04, 0x30, 0x5e, 0x2b, 0x24, 0x73, 0xf0, 0x58];
let mut output = "goodbye w®ld".to_owned();
bs58::encode(input).into(output.as_mut_str())?;
assert_eq!("he11owor1d\0ld", output);
