}Required Methods§
sourcefn get_download_path(&self) -> Result<PathBuf, ProtoError>
fn get_download_path(&self) -> Result<PathBuf, ProtoError>
Return an absolute file path to the downloaded file.
This may not exist, as the path is composed ahead of time.
This is typically ~/.proto/temp/
sourcefn get_download_url(&self) -> Result<String, ProtoError>
fn get_download_url(&self) -> Result<String, ProtoError>
Return a URL to download the tool’s archive from a registry.
Provided Methods§

to_file: &'life1 Path,
from_url: Option<&'life2 str>

Download the tool (as an archive) from its distribution registry into the ~/.proto/temp folder and return an absolute file path. A custom URL that points to the downloadable archive can be provided as the 2nd argument.
