Struct perseus::stores::immutable::ImmutableStore

pub struct ImmutableStore { /* private fields */ }

An immutable storage system. This wraps filesystem calls in a sensible asynchronous API, allowing abstraction of the base path to a distribution directory or the like. Perseus uses this to store assts created at build time that won’t change, which is anything not involved in the revalidation or incremental generation strategies.

Note: the .write() methods on this implementation will create any missing parent directories automatically.

Implementations

impl ImmutableStore

pub fn new(root_path: String) -> Self

Creates a new immutable store. You should provide a path like dist/ here.

pub async fn read(&self, name: &str) -> Result<String, StoreError>

Reads the given asset from the filesystem asynchronously.

pub async fn write(&self, name: &str, content: &str) -> Result<(), StoreError>

Writes the given asset to the filesystem asynchronously. This must only be used at build-time, and must not be changed afterward.

Trait Implementations

impl Clone for ImmutableStore

fn clone(&self) -> ImmutableStore

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImmutableStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
