Struct Index 

pub struct Index { /* private fields */ }

The registry index, read over the network.

Implementations

impl Index

pub fn new() -> Self

The public index.

The offline variable is the host saying the network is not there, which is a stronger statement than a flag nobody passed. A read that would otherwise fail slowly at a name it cannot resolve refuses at once instead.

pub const fn offline(self, offline: bool) -> Self

Refuse every read, for a caller that declared itself offline.

pub fn with_root(self, root: &str) -> Self

Read another index root, for a test that serves its own.

pub fn latest_version(&self) -> Result<Version, AppError>

The newest stable release the registry serves.

Errors

AppError::Refused when the caller is offline, when the index cannot be read, or when it lists no stable version.
