Implementations

impl MetadataCache

pub fn new(cache_repo_dir: &Path, repo_url: &str) -> MetadataCache

new Cache($io, $config->get('cache-repo-dir').'/'.preg_replace('{[^a-z0-9.]}i', '-', Url::sanitize($url))).

pub fn provider_key(file_name: &str) -> String

provider-<name with / -> ~>.json.

pub fn read(&self, key: &str) -> Option<Vec<u8>>

pub fn age(&self, key: &str) -> Option<u64>

Cache::getAge: age of the file in seconds.

pub fn write(&self, key: &str, contents: &[u8])

Atomic write (temp + rename), like Cache::write; a failure is silent (Composer carries on without cache).

pub fn with_last_modified( data: &Value, last_modified: &str, escaped: bool, ) -> Option<Vec<u8>>

The content to write when the server provided Last-Modified: $data['last-modified'] = ... then compact JsonFile::encode, with JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE for package files (asyncFetchFile), with flags 0 (slashes and unicode escaped) for packages.json and the includes (fetchFile).
