Struct RuntimeProvenance 

pub struct RuntimeProvenance {
    pub origin: String,
    pub installed_at: i64,
}

The provenance of an installed runtime.

Fields

origin: String

installed_at: i64

Install time, epoch milliseconds.

Implementations

impl RuntimeProvenance

pub fn new(origin: impl Into<String>) -> Self

A provenance for origin, stamped installed-now.

pub fn community() -> Self

A provenance marking a community install.

pub fn is_community(&self) -> bool

Whether this marks a community runtime (which must run contained).

pub fn read(directory: &Path) -> Option<Self>

Read the provenance from directory, or None if absent or unreadable. Unlike the quarantining store reads, a malformed provenance is left in place (reading it must not mutate the runtime’s directory).

pub fn write(&self, directory: &Path) -> Result<(), StoreError>

Write the provenance into directory.
