Implementations

impl Update

pub async fn download<C>(&self, on_chunk: C) -> Result<Vec<u8>>

where C: FnMut(usize),

Downloads the selected artifact and verifies its detached minisign signature.

The chunk callback receives the total number of bytes currently fetched for this download operation.

pub fn install(&self, bytes: &[u8]) -> Result<()>

Installs already-downloaded artifact bytes using the selected platform backend.

pub async fn download_and_install<C>(&self, on_chunk: C) -> Result<()>

where C: FnMut(usize),

Downloads, verifies, and installs the selected update in one step.

Trait Implementations

impl Clone for Update

fn clone(&self) -> Update

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Update

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

Formats the value using the given formatter.
