Struct bech32::Bech32Writer

pub struct Bech32Writer<'a> { /* private fields */ }

Allocationless Bech32 writer that accumulates the checksum data internally and writes them out in the end.

Implementations

impl<'a> Bech32Writer<'a>

pub fn new(
    hrp: &str,
    variant: Variant,
    fmt: &'a mut dyn Write
) -> Result<Bech32Writer<'a>, Error>

Creates a new writer that can write a bech32 string without allocating itself.

This is a rather low-level API and doesn’t check the HRP or data length for standard compliance.

pub fn finalize(self) -> Result

Write out the checksum at the end. If this method isn’t called this will happen on drop.

impl<'a> WriteBase32 for Bech32Writer<'a>

fn write_u5(&mut self, data: u5) -> Result
