Trait SidecarCache 

pub trait SidecarCache:
    Serialize
    + DeserializeOwned
    + Sized {
    const EXTENSION: &str;

    // Provided methods
    fn cache_path_for<P: AsRef<Path>>(fasta_path: P) -> PathBuf { ... }
    fn write<P: AsRef<Path>>(&self, fasta_path: P) -> StoreResult<PathBuf> { ... }
    fn load_if_fresh<P: AsRef<Path>>(fasta_path: P) -> Option<Self> { ... }
}

Trait for FASTA sidecar cache files (e.g. .refget.json, .seqcol.json).

Provides default implementations for cache_path_for, write, and load_if_fresh based on the cache file extension.

Required Associated Constants

const EXTENSION: &str

The sidecar file extension (e.g. "refget.json", "seqcol.json").

Provided Methods

fn cache_path_for<P: AsRef<Path>>(fasta_path: P) -> PathBuf

Return the standard cache path for a given FASTA file.

fn write<P: AsRef<Path>>(&self, fasta_path: P) -> StoreResult<PathBuf>

Write the cache to its standard sidecar path.

fn load_if_fresh<P: AsRef<Path>>(fasta_path: P) -> Option<Self>

Try to load a cache file for the given FASTA, returning None if the cache is missing or stale (older than the FASTA or its index).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl SidecarCache for DigestCache

const EXTENSION: &str = "refget.json"

impl SidecarCache for SeqColCache

const EXTENSION: &str = "seqcol.json"
