Struct ProxyWriter 

pub struct ProxyWriter<W> { /* private fields */ }

A RepositoryWriter that proxies operations to an inner writer.

The behavior of each I/O operation can be configured to facilitate customizing behavior. It also records operations performed. This makes this type useful as part of testing and simulating what would occur.

Implementations

impl<W: RepositoryWriter + Send> ProxyWriter<W>

pub fn new(writer: W) -> Self

Construct a new instance by wrapping an existing writer.

The default behavior for path verification is to call the inner writer.

pub fn into_inner(self) -> W

Return the inner writer, consuming self.

pub fn set_verify_behavior(&mut self, behavior: ProxyVerifyBehavior)

Set the behavior for RepositoryWriter::verify_path().
